The system is simple. If an exercise says 50 reps, you are doing 50 reps however you can. You can do 10 sets of 5 reps, 5 sets of 10 reps, 2 sets of 25 reps. It doesn’t matter. All that matters is that you finish 50 reps with perfect form. Once you complete the reps of one exercise, move on to the next exercise.
Pushups Beginner: 25 Reps Advanced: 50 Reps
Dips between chairs Beginner: 20 Reps Advanced: 50 Reps
Row between chairs Beginner: 30 Reps Advanced: 50 Reps
Sit-ups Beginner: 30 Reps Advanced: 100 Reps
Bent-leg raises Beginner: 25 Reps Advanced: 50 Reps
Bent-over twists Beginner: 25 Reps Advanced: 50 Reps
Knee bends (squats) Beginner: 25 Reps Advanced: 50-70 Reps
Calf raises Beginner: 25 Reps Advanced: 50 Reps
Chin-ups Beginner: 10 Reps Advanced: 30 Reps
If you cheat at an exercise, you are only cheating yourself. Don’t let your ego do the movements for you.
