Things to leave in the past: people, pastimes and programs that waste precious minutes you don't have and fail to help you make good on your goals. That's why this challenge is made up of express workouts that require 20 mins or less but still offer gains and inspiration to make positive changes. Designed by PT Ariel Belgrave, creator of L.E.A.N. Method fitness and nutrition coaching, each workout meets you where you are – whether you want to lift heavier or shake off newbie nerves – while pushing you to the next level.
The real gems in this challenge are the tough-yet-effective compound moves that work multiple muscle groups and joints at the same time. And get this: resistance-training programs involving multi-joint exercises (think: a deadliftor squat) are more effective for improving overall fitness than just doing isolated moves (such as a basic biceps curl), studies have found. “Including these types of exercises in your plan is a huge win if you're short on time, because you're still able to build lean muscle mass,” says Belgrave.
