**NB: The reason why high-intensity interval sessions work from some people and not others is simply b/c hard core exercisers understand that high-intensity means just that - going all-out with each set. So challenge yourself. Day one is pretty manageable, Day two and three, however, will really test your motivation and ability. This HIIT session is a follow-up to the well received v.1 program with the same name. The idea behind this workout is to take a break from traditional sets/reps. based workouts for a while. The body always loves a new training stimulus. Working with interval based workouts, like this one, are ideal for keeping your muscles under tension - typically - for longer duration compared to traditional workouts. One of the key components to getting stronger is known as time under tension, commonly referred to as TUT. It's critical to "stress" your muscles with the appropriate amount of TUT. And yes, most people simply don't check this box off. Each subsequent workout has a longer TUT and therefore is more challenging than the previous session. Day 1: Includes 8 exercises - all are supersets. TUT = 35 seconds. Metabolic Booster: Mountain Climbers to complete your workout. Equipment needed: dumbbells only. Day 2: Offers 8 exercises - all are supersets. TUT = 20-40 seconds. Metabolic Booster: Jump Rope (of no jump rope available - jump in place). Equipment needed: dumbbells, kettlebells & jump rope. Day 3: Has 8 exercises - all are supersets. TUT = 45 seconds. Metabolic booster: Medicine Ball Slams. Equipment needed: machines and free weights. Note: if you can’t get to a gym / you can do the workout with dumbbells or exercise bands. No excuses! Stay Stronger, Michael Wood, CSCS JeFit Team Member
