Build Upper-Body Strength Without Ever Doing a Push-Up — Try This Trainer's 5 Exercises

Dumbbell pullovers work the muscles in your chest, Jones said.

• Begin lying face up with your feet flat and knees bent, holding a dumbbell at your chest. Press the dumbbell up over your chest with your thumbs wrapped around the base of the weight and arms straight.
• Extend your arms back until the biceps are in line with the ears. Pause, engage your abs and chest, and make sure your back is flat on the ground.
• Continue to keep your back flat as you pull the weight over your chest with straight arms. This counts as one rep.
