The Fat Loss Inferno workout consists of 5 total weight lifting days. Two of the days will focus on legs, two of the days will focus on back, and the week as a whole will prioritize hitting each muscle group with the optimal training frequency given the volume. The final day of the week is a back and chest superset workout (a pairing made famous by Arnold himself) to help you burn even more calories while getting a nice upper body pump for the weekend. Ab work isn’t included into the program design. But, including core work and cardio into the program can prove to be beneficial depending on your individual goals. If you wish to do so, you can include core and cardio training into your morning routine on whichever training days you prefer or on your rest days. Rest periods during the workouts should be approximately 60-90 seconds in between each exercise. I’d recommend resting for 90 seconds for the first lift of each workout, 75ish seconds for the next exercise, and 60ish seconds for the remainder of the exercises. All exercises should be performed at an RPE of between 7-9, with the majority of your working sets using a weight in which you have 1 rep in reserve after each set. If you’re unsure of what weight to use, you may want to experiment for the first couple of weeks until your body gets used to the program and you have a better understanding of your individual strength levels. Adding additional workouts or exercises to the program, outside of core and cardio training, is not recommended.
