3. Fitted Lifts ($2.99; IOS)
Variance’s Fitted Lifts (iOS) is for experienced athletes who have been using pen and paper to record their weightlifting sets. You can create a routine from a list of exercises within the app’s database or, if necessary, add your own. Exercises are grouped according to the muscle group they focus on, such as chest or triceps. Fitted Lifts includes custom rest timers for each exercises, which takes the guesswork out of resting between sets. As you log your routines, Fitted Lifts can display your progress in a table or graph; the app also tells you how long it’s been since your last workout for a specific muscle group.
