Forget complicated exercises where you lift a dumbbell, twist your body, and move your feet at all once. Bodyweight moves such as squats, push-ups, and jumps of every variety are back in vogue, Olson says, because you can do them anywhere and hit all of the major muscles in the body, plus they're dynamic, can be performed faster than lifting dumbbells or a barbell, and increase both strength and endurance.
This "back to basics approach" also includes retro-style training techniques, such as crawling movements, jumping jacks, and one-arm push-ups, Tumminello adds. “The more we learn about what works, the more we realize that many of the old-school training concepts, like climbing ropes, push-ups, bear crawls, deadlifts, and hill runs, are some of the most effective ways to train,” he says.
