12 Best Weightlifting Exercises to Help You Lose Weight

Push-ups are "great for building muscles in your arms and stabilizing your core," says Stephanie Blozy, an exercise-science expert and the owner of the Fleet Feet store in West Hartford, CT. She suggests starting push-ups with your knees resting on the floor and moving up to a classic push-up with straight legs.

• Begin in a plank position with the arms and body straight, shoulders over the wrists. Keep the core engage.
• Bend the elbows behind you and lower your chest to the floor. Keep your upper arms tight to your body so your elbows are against your ribs on both sides.
• Straighten the arms, coming back to plank position. That's one rep.
• Do three sets of 8-10 reps.
