Yes. The program of 4 workouts is designed to be repeated on whatever timeline suits you. It is not necessarily meant to be completed weekly. If you work out twice a week, you'll cycle through the program every 2 weeks. If you work out 3 times a week, you'll complete the program about every 10 days. You will still get great full-body coverage on 2 or 3 workouts a week, provided you do the workouts in order.

The rest periods are there to help you recover well enough to lift with good form and enough intensity on the next set. For heavier compound movements, longer rests usually lead to better performance, better progress, lower injury risk and less technique breakdown than rushing between sets. However, you can adjust the rest time by tapping on it if you wish.

Research shows rest between sets reduces fatigue and injury risk. For this reason, Fortify doesn't use supersets.

Fortify currently uses linear progressive overload training rather than built-in periodization. If you want a deload workout, try Return After a Break; it reduces weights by about 20%. If you're looking for a different style of periodization, email support and let us know what you'd like to see.

Fortify tracks how many times you've completed each workout and will prompt you to refresh it after completing it 8 times.

Open the workout you plan to do, tap the menu in the top right, and choose Return After a Break. It will reduce the weights in your workout by about 20%, without changing your 1RM or progress stats. Next time you do this workout, the weights will be back to their previous levels.
