Valen - Gym & Recovery Tracker

Valen is a gym tracker that shows which muscles are ready to train. As you log workouts, it builds a recovery heatmap of your body, split into sub-zones like upper and lower chest, quads and hamstrings, or front and rear delts, so you can decide between push, pull or legs based on what has recovered.

Recovery is estimated from your logged training, not measured by a wearable, so it is a guide rather than a lab reading. It suits lifters who train without a fixed split and want a quick answer to what to hit today.
