Sometimes it’s hard to keep up with cardio workouts for long periods. Instead of giving up, try doing some active rest exercises when it gets too tough.
Do 10 lunges: step forward as far as you can with one leg and lower down into your knee. Keep your back straight and aim to create a 90-degree angle in both knees.
Push-ups. If you (still) can’t do full push-ups: practice from your knees or with your hands on a bench. Try to keep your back as straight as possible.
If you pass a picnic bench while running, try doing 10 dips. Place your hands on the edge of the seat, bend your knees, and lower yourself down—like a reverse push-up with your arms. Don’t shrug your shoulders toward your ears!
Do a few squats: act like you’re going to sit in a chair—but leave the chair out. Keep your back straight and don’t let your knees go past your toes.
Mix up your cardio routine with different variations. Instead of long-distance sessions, try shorter but more intense intervals.
Do a few stretching exercises. Midway through your workout, your muscles are well warmed up and stretching becomes easier.
