## What is CheckFit?

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.

FEATURES (included with your subscription)
• Personalized strength training programs
• Matched to your goals, equipment, and schedule
• Progressive overload built into every program
• Adaptive weekly adjustments
• Fast workout logging
• Strength and performance tracking
• Progress insights over time
• Made for serious gym training

No social feed. No endless scrolling. No distractions.

Just a plan, your workout, and the data that proves you're getting
stronger.

Stop guessing. Start growing.

SUBSCRIPTION
• Monthly — $20/month

### 5/5 — Good Motivator to Lift

*2026-09-22*

This is the first app I used that actually motivated me to lift daily. I started during the beta test nearly 90 days ago and have become significantly stronger since. The app is simple, it tells me what to lift based on a survey of my time and equipment access, and it builds a six week program. Every time I strength train I check off my sets. Done. Easy. Motivating.
