THE 22-MINUTE WORKOUT
In the arms (and legs and tummy) race to make workouts faster and more effective, a new player stands out. Trainer Bryant Johnson — the dude behind Ruth Bader Ginsburg’s famous pushups — says you can accomplish everything a workout needs to accomplish in 22 minutes daily: 10 of cardio, 8 of weights, and 4 of stretching. It can all be done at home, without special gear.
The key, NPR reported, is that Johnson exploits the power of interval training. Just like a car consumes more energy with frequent changes in speed, so do we. That means burning more calories in less time.
