Push-ups work your chest, shoulders, triceps, and core, Nagel said. NASM-certified trainer Hannah Johnson added, "I love my clients to get some push-ups in, even if they are modified, as they are a powerhouse exercise."
- Start in a plank position with your arms and legs straight, shoulders above your wrists.
- Take a breath in, and as you exhale, bend your elbows out to the sides and lower your chest toward the ground. Stop as soon as your shoulders are in line with your elbows. Inhale to straighten the arms. This counts as one rep.
- To modify, do this exercise with your knees on the floor.
