Adaptive Strength Training
Only for iPhone

The workout plan that evolves with every workout.
You've been showing up. Three, four, maybe five days a week. You've put
in the work.
But building muscle isn't just about effort. It takes the right training
and a plan that adapts as you get stronger.
Most fitness apps tell you what happened.
CheckFit tells you what to do next.
CheckFit is a subscription app. A paid subscription is required to
generate and follow a program, and new members start with a 7-day free
trial.
Get a personalized strength training program built around your goals,
experience, equipment, and schedule. Every workout is planned for you,
so you can focus on lifting—not deciding what to do.
As you train, CheckFit adapts. Your weights, volume, and progression
evolve based on your performance, helping you continue making progress
without guesswork.

• Personalized strength training programs

stronger.
Stop guessing. Start growing.
