Fitbod

Fitbod generates customized workout programs using an AI model trained on over 100 million workouts. Its core differentiator is muscle fatigue modeling — it knows which muscles you worked last time and programs the next session to hit fresh muscle groups while letting fatigued ones recover.

## Muscle Fatigue Algorithm

After each workout, Fitbod updates your muscle recovery model. It knows that your chest is at 60% recovery but your back is fully fresh. The next workout is programmed to emphasize recovered muscles while incorporating lighter work for others — the same logic a good personal trainer uses intuitively, but computed automatically.

## Adaptive Progressive Overload

Fitbod tracks your performance on each exercise (weight lifted, reps, sets) and incrementally increases difficulty as you adapt. It doesn't add weight arbitrarily — the algorithm models your strength curve per exercise and times increases to when you're ready to progress. Over months, this creates measurable strength gains without plateaus.

## Equipment Flexibility

Fitbod works with any equipment setup: full commercial gym, home gym with dumbbells, barbell and rack, or bodyweight only. When you set your available equipment, the exercise library adapts — you'll only see exercises you can actually do.

## Exercise Video Library

Every exercise includes a video demonstration from multiple angles with form cues. 1,400+ exercises cover barbell, dumbbell, cable, machine, and bodyweight movements.

## Goals and Customization

Supported goals: muscle gain, strength, endurance, weight loss, general fitness. Users can set goal muscle groups (want to emphasize glutes or arms), set training frequency, and block exercises they don't like.

## Pricing

Free: 5 workouts. Elite: $12.99/month or $79.99/year.
