Assay — Adaptive Training

Your apps track.
Your training should respond.

Your workout log knows what you lifted. Your wearable knows how you slept. Your food log knows what you ate. But connecting those numbers to what you should do next still falls on you.

Assay closes that gap.

It brings your training, recovery and nutrition together, builds your strength plan around your goals, and adjusts planned sessions as your recovery, performance and circumstances change.

YOUR BODY REPORTS IN
Connect Apple Health and Assay compares your sleep, heart rate variability (HRV) and resting heart rate with your own baseline. The same number can mean different things for different people. Your recent history gives it context.

YOUR TRAINING ANSWERS
A rough night? Assay can reduce today’s planned work and show the reason.
Last session felt easy? Your logged reps, weight and effort help guide the next prescription.
Less time today? Shorten the session to fit.

Your recovery becomes something your training can respond to.

YOUR GYM. YOUR EQUIPMENT. YOUR TIME.
A plan should work in the room you’re actually training in. Build sessions around the equipment at your gym, at home or when travelling. Change locations, swap an exercise or adjust your available time—and keep training.

FOLLOW YOUR BODY’S RESPONSE
Track your weight, body composition and training by muscle group. Connect a compatible Withings scale for additional measurements. Supported left/right muscle measurements can guide extra work for the weaker side.

FUEL YOUR TRAINING
Give your eating a purpose with calorie and protein targets built around your goal. Log meals manually or save your usual meals for quick entry. With Premium, log from a photo or describe what you ate.

YOUR WEEKLY REVIEW
With Premium, review your training and nutrition, revisit previous targets and set priorities for the week ahead. Ask Coach about your plan and history. Coach chat can propose changes to your plan for you to confirm.
