Frequently asked
Which workout app swaps the exercise when a machine is taken or the gym is busy?
AGUNA. In a session, Machine taken? lets you do another exercise now and moves the busy one to next, so nothing is skipped, and Busy gym? switches every remaining exercise to a dumbbells-only version for the same muscles, sets and reps, with one tap back to your full plan. Fitbod, Boostcamp and Planfit let you replace a single exercise instead. See how both work.
