For lifters who choose their own training

Plan on a bigger screen, take your workout to the gym on iPhone, and keep training, nutrition and check-ins in one place. Free includes the ready-made programs; Pro lets you build your own.

Know the limits before you start

There is no Android app. Strengthara does not automatically suggest weights or reps. You see Last time and your record, and choose your next set yourself.

What goes in a Block?

A Block brings together a program of workouts, a nutrition plan and check-ins. It has no fixed dates or length. Keep several Blocks and make one active when you want to train from it.

With Pro, build your own Block and edit its program and nutrition plan.

Plan it. Train it. Review it.
