How JEFIT's Deep Training Analysis Helps You Train Better
Every set you log is data about how you train. Read well, it shows what's working, what to change and what to train next.
JEFIT turns that data into four kinds of analysis: strength, volume, balance and recovery. Each one helps on its own. Read together, they show not just whether you're progressing, but why, so every session builds on the last.
Key takeaways
- JEFIT's training analysis answers four questions: am I getting stronger, am I doing enough work, is the work going to the right muscles, and am I recovering between sessions.
- Read them in that order. A stalled lift is the symptom; the cause is usually in the volume, balance or recovery data behind it.
- More sets build muscle, but they don't always build strength. In trained men, 5 sets per exercise grew more muscle than 1, with no difference in strength gains (Schoenfeld et al., 2019).
- Check it on three timescales: the workout summary after every session, the Progress Index and Muscle Recovery chart weekly, and the 1RM trend monthly.
- JEFIT Elite reads your training against targets: the Progress Index, JEFIT Insights and the long-range Progress tab views. The 1RM chart, Muscle Recovery chart and workout summary come with every account.
How does JEFIT use different analyses to help you progress?
JEFIT reads the sets you log through four kinds of analysis (strength, volume, balance and recovery), so you can see not just whether you're progressing, but why.
Together they form JEFIT's training analysis: the set of charts and scores that turns the sets you log into answers about your training: whether you're getting stronger, doing enough work, spreading it across your muscles, and recovering between sessions. Every number comes from what you actually logged: weight, reps, sets and the time between them.
The point isn't the stats. It's deciding what to train next.
If you build your own plan, you read the analysis to adjust it. If you train on the Adaptive Plan, it reads the same data and adjusts the plan for you.
This guide is for lifters who log their sessions and want to know what the numbers say. The data shows patterns, not diagnoses: if a joint hurts, see a professional rather than a chart.
What does each JEFIT analysis measure?
Strength is read on the 1RM chart and the Progress Index, volume on sets per muscle and Stimulus Volume, balance on BodyMap and Movement Balance, and recovery on the Muscle Recovery chart. The table shows where each one lives and whether it comes with every account or with Elite.
| Question | Analysis | What it shows | Where in JEFIT | Tier |

| Calendar and streak | How often you train, as a calendar heatmap | Progress tab | Every account | |
| JEFIT Insights | A workout score per session, and where your time went: rest, loading plates and adjusting machines, and actual training | Progress tab → Fitness Insights | Elite |
Every chart reads the same log. That's what makes it possible to read them together: a change in one shows up as a cause or an effect in another.
How do JEFIT's analyses work together?
Read the four questions in order: strength first, then volume, then balance, then recovery. Strength is the result you care about. The other three are where the reason for that result usually is.
1. Am I getting stronger? The 1RM chart and Strength by pattern
Your estimated 1RM is the heaviest weight you could lift for one rep, worked out from the weight and reps you log. It is the most direct read on strength because it turns every set into one comparable number.
Without it, progress is hard to see. A week of 100 lb for 10 reps can look like a step back from 120 lb for 5. The 1RM chart puts both on the same line.
- What it reads: every set you log for that exercise. Each set shows its own 1RM, and the chart shows the trend with the min and max for the range, from 14 days to lifetime.
- How accurate it is: estimates from sets of 10 reps or fewer tracked tested 1RM closely in one study, with R² of 0.93 or higher for chest press and leg press (Reynolds, Gordon and Robergs, 2006). Read the trend on your heavier sets.
- What to look for: a rising line means the plan is working. A flat one for three weeks or more means something needs to change.
The 1RM chart is per exercise. Strength in the Progress Index (Elite) reads your progress by movement pattern. It groups your lifts into six patterns: vertical push, vertical pull, horizontal push, horizontal pull, hinge and squat.
Patterns matter because they show what kind of movement is lagging, not just which lift. If every pressing lift is up and every hinge is flat, that points to your program, not to one exercise. The Strength Engine explains how the pattern read is calculated.
2. Am I doing enough work? Weekly volume, volume per muscle and consistency
Check work at three levels: how much you did in total, how much each muscle got, and whether you did it week after week. Too little effective work is the first thing to rule out when a lift stops moving.
- Weekly volume. The Progress tab adds up your total volume (weight × reps across every set) and your workout time for the period. It shows whether your overall work is rising, holding or falling.
- Volume per muscle. Total volume can rise while one muscle gets almost nothing. Sets per muscle group shows the split on every account. With Elite, Stimulus Volume counts effective sets, called Hard Set Equivalents: about one for each hard set taken close to failure, credited to the muscles that drive the movement. Each muscle is shown against its weekly target, for example "Chest: 6 / 12".
- Consistency. Weekly volume only counts if it happens every week. Sets per muscle group shows how often each muscle comes up; the calendar heatmap and your streak show whether you train week after week.
Why per muscle matters: more weekly sets per muscle produced more muscle growth across the range studied (Schoenfeld, Ogborn and Krieger, 2017). Why frequency matters: training a muscle at least twice a week produced larger growth than once a week (Schoenfeld, Ogborn and Krieger, 2016).
One limit to keep in mind: in trained men, 5 sets per exercise grew more muscle than 1, with no difference in strength (Schoenfeld et al., 2019). Once a muscle is in its target band, more sets mainly add size. If strength is the goal, look at balance and recovery next. The Stimulus Volume Engine covers how effective sets are counted.
3. Is the work going to the right places? Muscle balance and pattern balance
Enough work can still be in the wrong places. Check balance two ways: by muscle and by movement pattern.
- Muscle balance. BodyMap on the Workout Complete screen shows which muscles a session hit. With Elite, it breaks each muscle group into its parts, for example back into middle back, lower back, upper back and lats. The training muscle breakdown on the Progress tab shows the same split over weeks.
- Pattern balance. Movement Balance (Elite) compares effective sets across opposing patterns: vertical pull to push, horizontal pull to push, and hinge to squat. About 1:1 reads as balanced, around 1.5:1 as a mild skew and 3:1 or more as severe.
Balance protects the progress you've made. A lift can stall because a supporting muscle is undertrained, even when total volume looks fine. A push-heavy week is the usual skew. Exercise choice matters for the shoulders too: in recreational lifters, shoulder impingement was associated with upright rows and lateral raises above shoulder height, and inversely associated with external rotator strengthening (Kolber et al., 2014), so external-rotator work earns its place. The Movement Balance Engine goes deeper on the ratios.
4. Am I recovered enough to use it? The Muscle Recovery chart
Plenty of well-spread work still won't pay off if you train the same muscle before it has recovered.
- Muscle Recovery chart. A body map where recently trained muscles are dark and recovered ones are light. Each muscle shows a recovery rate and recovery time, worked out from how hard you trained it and how long ago.
- Calendar. Shows whether sessions are stacking up back to back.
- JEFIT Insights (Elite). A workout score for each session, plus how your time split between rest, loading and training. A falling score while the weights stay the same is a sign of fatigue.
Recovery takes longer than it feels. Muscle protein synthesis was more than doubled 24 hours after a hard session and close to baseline by 36 hours (MacDougall et al., 1995). The Adaptive Plan reads the Muscle Recovery chart when it picks which muscles to train.
The rule that comes out of this: when strength stalls, check the work before the effort. Pushing harder on the same plan rarely fixes a problem that the volume, balance or recovery data is already showing you.
Common training questions, and how JEFIT answers them
Most lifters don't open their stats with a chart in mind. They open them with a question. Each answer below uses more than one analysis, because the answer usually sits in more than one place.
1. How do I know an exercise has stalled, and how does JEFIT help me get past it?
An exercise has stalled when its 1RM trend has been flat for three weeks or more and no new PRs have shown up. Your exercise history will show the same weight and reps, session after session.
- Confirm it: check the 1RM chart for the lift. With Elite, check whether its whole movement pattern has stalled in Strength, or just that one exercise.
- Find the cause: follow the loop. Is the muscle getting enough effective sets? Is the opposing pattern keeping up? Is the muscle recovered when you train it?
- Get past it: fix the one signal that's out of line. With Elite, Load Progression suggests your next weight and reps from the sets you logged and your goal, so each session builds on the last. You can always override a suggestion.
2. I've followed the same plan for months. How do I keep improving?
A plan that worked for months can stop working because your body has adapted to it. Training load has to keep increasing as you adapt (ACSM, 2009).
- Check whether it's still working: open the 1RM chart in the 3-month view, and your top 3 lifts by 1RM on the Progress tab. Flat lines across your main lifts mean the plan has stopped moving you forward.
- Find what's missing: the Progress Index shows which of Strength, Stimulus Volume and Movement Balance is out of its target zone.
- Change the progression, not just the exercises: keep your plan and turn on Periodization on your own plan (Elite), which runs it in phases and adjusts how much you lift each week. Or let the Adaptive Plan build a new plan in four-week blocks that updates from what you log. Your existing plans stay as they are.
3. How do I know if my plan is a good plan?
A good plan does four things: it makes you stronger over time, gives every muscle enough effective work, keeps your movement patterns balanced, and leaves room to recover. Each is one of the four analyses.
- Before you run it: open a day in the plan and tap the BodyMap icon on Day Details to see which muscles that day hits (the % breakdown is Elite). Days that never reach a muscle group show up here first.
- After four weeks: read the Progress Index and the 1RM trend together.
| What you see after four weeks | What it says about the plan | What to change |
|---|---|---|
| All three in zone, 1RM trending up | It's working | Keep going; don't change what works |
| Stimulus Volume below zone, strength flat | Not enough effective work | Add hard sets to the muscles below their band |
| Volume in zone, Movement Balance skewed | Enough work, unevenly spread | Shift sets toward the weaker side of the pair |
| Volume above zone, strength flat, recovery chart dark | More work than you're recovering from | Cut sets or add a rest day before adding anything else |
4. One of my muscles isn't improving. What should I do?
A muscle that isn't growing is usually getting too few effective sets, trained too rarely, or trained before it has recovered. Check all three before you add more.
- How much work it gets: sets per muscle group, and with Elite, its Stimulus Volume against its weekly target.
- Where in the muscle the work goes: the BodyMap % breakdown (Elite) splits a group into its parts. Back at 60% of a workout can still mean lats at 0%.
- How often it comes up: sets per muscle group, read week by week. A muscle trained once a week is a common culprit.
- Whether it's recovered: the Muscle Recovery chart at the start of the session that trains it.
What to change: add sets on a second day before piling more onto one. With Elite, tap the muscle in BodyMap to add an exercise for it, or swap an exercise on the log screen for a recommended alternative.
5. How do I know if a session was efficient?
An efficient session gets the planned work done in the time you have. The workout summary and JEFIT Insights show whether it did.
- Workout summary (every account): training time, total volume, sets performed, PRs and your session RPE. Compare it with the last time you ran the same workout.
- JEFIT Insights (Elite): a workout score for comparing sessions at a glance, and a time breakdown of rest, loading plates and adjusting machines, and actual training.
- What to look for: if rest and setup take more of the session than lifting, group exercises by equipment, use supersets, or tighten your rest timer to fit your goal.
How often should you check your training analysis?
Check it on three timescales. Each answers a different question, and checking the long-range charts every day mostly shows noise.
- After every session: open the workout summary (time, volume, sets, PRs, BodyMap). It answers: did today's session do what it was meant to?
- Once a week: open the Progress Index, the Muscle Recovery chart and sets per muscle. They answer: is this week's work enough, balanced and recoverable?
- Once a month: open the 1RM chart (3M view), your top 3 lifts by 1RM, the training muscle breakdown and the calendar. They answer: am I getting stronger, and is my training consistent?
What does JEFIT Elite add to the analysis?
JEFIT Elite adds the analyses that read your training against targets: the Progress Index, JEFIT Insights and the long-range views. The core charts come with every account.
| JEFIT Elite adds | Every account includes |
|---|---|
| Progress Index: Strength, Stimulus Volume (weekly set targets) and Movement Balance | 1RM chart, personal records and full log history |
| JEFIT Insights: workout score, sets volume, records per muscle and workout time analysis | Workout summary: training time, total volume, sets, PRs, RPE and BodyMap |
| 1RM analysis: record breakers and the trend across your lifts | Training volume and sets per muscle group |
| BodyMap % breakdown, with add-exercise from the map | Muscle Recovery chart |
| Progress tab over 1 month, 12 months and lifetime | Progress tab over 7 and 14 days, calendar view and streak |
| The Adaptive Plan, which reads this analysis and adjusts your plan for you | Body stats and progress photos |
What are the most common mistakes when reading training data?
- Reading one chart alone. A flat 1RM trend tells you something is wrong, not what. Follow it into volume, balance and recovery before changing anything.
- Changing three things at once. Fix one signal, then read again. Otherwise you can't tell what worked.
- Judging strength on a single session. One bad day is noise. Read the 1RM chart over a month or more.
- Treating more volume as the answer to everything. Volume drives muscle growth, but once you're in your target band, strength often needs better balance or recovery, not more sets.
- Logging some sets and skipping others. The analysis is only as complete as your log.
Bottom line
- If your 1RM is flat and Stimulus Volume is below its band, add hard sets.
- If your 1RM is flat and volume is already in its band, check Movement Balance and the Muscle Recovery chart before adding anything.
- If one muscle lags in the breakdown, train it on a second day before you add more sets to the first.
- If sessions feel flat and the recovery chart stays dark, cut work or spread it out.
- If everything is in its zone and your 1RM is rising, keep going.
Where can you go deeper on each analysis?
Each analysis has its own guide or feature page:
- Strength: The Strength Engine and the 1RM feature page.
- Volume: The Stimulus Volume Engine, mastering training volume and the best weekly volume for muscle growth.
- Balance: The Movement Balance Engine.
- Recovery: the Muscle Recovery feature page and optimal recovery time for strength training.
- All of it together: the Progress Index guide and gym performance tracking.
- Turning it into your next session: how Load Progression sets your next weight and reps, following the principle that training load has to increase as your body adapts (ACSM, 2009).
Quick answers: where to find your progress in JEFIT
Short answers to the questions lifters ask most, each pointing to where it lives in JEFIT.
How do I see my progress in JEFIT?
Look in four places. First, the 1RM chart for each lift, which shows whether you're getting stronger. Second, your personal records and exercise history. Third, the Progress tab for volume, workout time, your calendar and streak (gym performance tracking). Fourth, with Elite, the Progress Index, which reads your week against a target zone. For body changes, add body stats and progress photos.
How do I see my 1RM in JEFIT?
Open the exercise on the log screen and tap the chart icon. The 1RM chart shows your estimated 1RM over 14 days to lifetime, with the min and max for that range, and each logged set shows its own 1RM. The Progress tab also lists your top 3 exercises by 1RM over the last 3 months.
How do I know if each muscle is getting enough sets?
Check it in two ways. Sets per muscle group counts the sets each muscle got, on every account. With Elite, Stimulus Volume in the Progress Index counts effective sets per muscle for the week and shows each one against its weekly target, so a muscle below its target stands out.
How do I check if my training is balanced?
Use three views. BodyMap on the Workout Complete screen shows which muscles a session hit. The training muscle breakdown on the Progress tab shows how your work splits across muscles over time. With Elite, Movement Balance compares vertical pull to push, horizontal pull to push and hinge to squat.
How do I see which muscles are recovered?
Open the Muscle Recovery chart on the Progress tab, under Body. Recently trained muscles are dark and recovered ones are light, and each muscle shows a recovery rate and recovery time, worked out from how hard you trained it and how long ago. Instant Workout uses the same data to build a session around what has recovered.
How do I see where my gym time goes?
Every workout summary shows the session's training time, and the Progress tab adds up your total workout time over a period. With Elite, JEFIT Insights breaks each session into rest time, loading time (loading plates and adjusting machines) and actual training time.
Can I track my progress in JEFIT without Elite?
Yes. Every JEFIT account gets the 1RM chart, personal records, full log history, training volume, sets per muscle group, the Muscle Recovery chart, the workout summary and the calendar. JEFIT Elite adds the Progress Index, JEFIT Insights and the 1-month-and-longer Progress tab views.
Does JEFIT show a single progress score?
No. The Progress Index shows whether your Strength, Stimulus Volume and Movement Balance are in, above or below your target zone, without a number, so a score doesn't become the goal. Each workout does get its own workout score in JEFIT Insights (Elite), for comparing sessions.
Do custom exercises count toward my stats?
They count toward the Progress Index once they're linked to a similar library exercise, one that works the same muscles and joints. Link your custom exercises so the Progress Index sees all of your training.
Do I need the Adaptive Plan to use JEFIT's analysis?
No. The analysis works on any plan, including one you built yourself, and you decide what to change. The Adaptive Plan reads the same data and makes those adjustments for you.
How long before JEFIT's analysis is useful?
The workout summary and Muscle Recovery chart are useful from your first session. The Progress Index is a week-to-date snapshot that runs Sunday to Saturday, so read it at the end of the week. The 1RM trend needs a few weeks on the same lifts.
