The best personal trainer apps, ranked

Ranked for someone who wants an app to do a trainer's job in the gym: write the plan, adjust it, and tell you what to lift. A human coach comes first because one can check your form and keep you showing up. The best free app comes next, for everyone who won't pay $150 a month for that; Future does trainwell's job for more per month, so it follows.

Week one in RIRLift, every lift new

The same beginner, machine shoulder press planned for 10 reps with 2 left, and a lat pulldown in its second session.

ExerciseYou loggedNext sessionWhy
Machine Shoulder Press50 lb (Estimate), 20 reps, nothing left60 lb × 10One max-reps set measures you. 20 to failure at 50 lb against 12 planned: 50 × 49 ÷ 41 ≈ 60 lb.
Neutral-Grip Lat Pulldown100 lb, 11 / 10 / 10 reps, 2 left (target 10)100 lb × 11The weakest set hit its target of 10. Same weight, aim for 11.

No max test, no guessing: the first set measured the press, and the pulldown moved one rep.
