Two seasons collide
Generic lifting plans assume the gym is your only priority. When your running mileage peaks right as your climbing season starts, a static gym plan leaves you too fatigued for either.
Proper multi sport athlete training builds a single base that serves your running, climbing and court play. Your coach programs three weekly gym sessions and puts the most carbohydrate on your sport days.

The problem
01
Generic lifting plans assume the gym is your only priority. When your running mileage peaks right as your climbing season starts, a static gym plan leaves you too fatigued for either.
02
Runners get shin issues, climbers get elbow pain, and cyclists lose their glutes. Standard plans ignore the specific prehab overlay each sport requires to keep you on the road or the wall.
03
Eating the same way every day ignores your varying output. When you follow a rigid diet, you risk undereating on heavy sport days and missing the recovery your body requires.
The method
01
Your coach builds a foundation of single-leg strength, pulling, and elastic power that transfers to every sport you play.
RuleThree gym sessions a week focused on compound strength and power.
02
On your practice days, you get short movement blocks targeted at the exact joints your sport stresses the most.
RuleA 15-minute prehab block added to your scheduled sport practice days.
03
Your daily protein target scales to your bodyweight across four meals. The rest of your plate shifts based on your training load.
RuleHigh carbohydrates on sport days, moderate on lifting days, lower on rest.
04
The plan watches your sleep and joint pain logs. If fatigue runs high for three days, your coach scales back the gym work.
RuleA scheduled deload every four weeks, or when fatigue hits seven.
Your week
Gym days start on Monday, Wednesday and Friday. Move any session in chat around your practice days and events, once or every week.
Built to adapt
Connect Apple Health or Health Connect. When sleep, HRV or resting heart rate say you are under-recovered, today's session gets lighter. Planned deloads follow your coach's schedule, and you can ask for one in chat.
Travelling, sore, short on time, missed a meal: tell your coach at any hour. It rebuilds the week or re-portions the day, and confirms the change in chat.
Daily check-ins and progress photos go to your coach, and your plan is adjusted from what actually happened, not what was scheduled.

Questions
Something else? Ask your coach in chat once you are in. It answers at any hour.
Tell your coach in chat when two seasons overlap and ask for a deload: that week's gym sessions drop to fewer sets at lower loads. The scheduled deload every four weeks stays in place.
Endurance athletes risk under-recovery if they miss fuel. Tell your coach in the chat, and it will re-portion your remaining meals for the day to hit your targets.
You need a trap bar, a bench, a pull-up bar, kettlebells, dumbbells, a medicine ball, a landmine and bands. A few lifts list a swap, such as push-ups for chin-ups, and you can swap any exercise in chat.
The three gym sessions run just under an hour. Practice-day prehab blocks take about 15 minutes, and a low-recovery reading makes your next session lighter.
The coach reads your sleep, resting heart rate, and HRV from Apple Health or Health Connect, and makes today's session lighter when your recovery is low.
