"This basic exercise works the full body and gets the heart pumping," Aldridge said. Do it as quickly as you can (with proper form) and you'll get double benefits: heart-pumping cardio and strength work in your upper and lower body.
- Start standing with your feet hip-width apart, core pulled in tight.
- Bend forward from your waist, keeping your chest lifted and core tight. Place your palms on the ground, bending your knees if needed.
- Walk your hands out until you're in a high plank position with your wrists directly below your shoulders.
- With your core engaged, bend at your elbows and lower your torso toward the mat to perform a push-up. Don't let your back slouch or hunch — try to keep it flat the whole time.
- Push through your hands to complete the push-up and return to the plank position.
- Reverse the movement, walking your hands back toward your feet and straightening up to return to standing.
- This counts as one rep.
