1. Squats: Stand tall with your feet slightly wider than hip-width apart. Hinge at your hips to sit your butt back and down. Push through your heels to return to standing and complete 1 rep. Here’s how to do the perfect squat.

  2. Knee push-ups: Start in a plank position with your hands flat on the floor about shoulder-width apart and bring your knees on the floor with your feet up in the air behind you. Keeping your body in one long line, bend your arms and lower yourself as close to the floor as you can. Then push back up to complete 1 rep. Here’s how to do the perfect push-up.

  3. Seated V-Ups: Start sitting with your legs extended and lifted off the floor a few inches. Lean back slightly and keep your hands on the floor near your hips. Straighten your legs as you lean your torso back, then bring your knees in your chest as you raise your torso to complete 1 rep.

  4. Mt. Climbers: Start in a high plank with wrists directly under shoulders, body in straight line from head to toe. Bring right knee under torso, then bring left knee under torso to complete 1 rep. Continue to alternate sides quickly.

  5. Planks: Place the forearms on the ground with the elbows aligned below the shoulders, and arms parallel to the body at about shoulder-width distance. If flat palms bother your wrists, clasp your hands together.
