Pushups are a barebones muscle-building exercise that's incorporated in nearly every major athlete's training program because they work. Simple as that. They target your arms Myles Garrett Hat , chest, and core, serving as one of the most efficient bodyweight movements you can do. Better yet, you can crank them out anywhere, anytime and easily up the intensity by changing the elevation, adding equipment Nick Chubb Hat , moving your hand and feet positioning, even adding instability. Actually, it's best you add some variety; exercise tedium is as bad for your motivation as it is for your muscles.

1) Wide-grip pushup

Target area: chest.

Start from a normal pushup position but spread your hands wider than shoulder length. This will force your chest to pick up the brunt of the work from your triceps and shoulders.

2) Narrow-grip pushup

Target area: triceps.

Do normal a normal pushup with your hands just a few inches apart from each other underneath your chest.

3) T-pushup

Target area: full-body workout.

Start from the pushup position. Take one hand off the ground and raise it straight up in the air (making a T-shape out of your body). Keep your eyes locked on your raised hand. Repeat for your other side. Add dumbbells to the routine to increase the intensity of the workout. "T-pushups hammer your entire upper body," says Yeung. "Not only are you targeting your chest, but you're also strengthening your shoulders, opening up your thoracic spine [midback] Denzel Ward Hat , and building rotational power through your core."

4) Single-leg pushup

Target area: intensifies work on upper body and core.
