Doubles
A training system for people who lift and run — built so that neither one wrecks the other.
The problem
Every marathon plan treats lifting as the thing you drop when the mileage climbs. Sixteen weeks later you have finished the race and lost the strength you spent years building.
What Doubles does
Doubles builds the running around the lifting instead. It reads every set and every mile as they happen and adjusts the plan to keep you on target — so race day arrives without the squat and the bench having quietly gone backwards.
Availability
Doubles is taking waitlist signups now. The product, pricing and signup live on its own site: doubles.fit.
