The Super Simple 7-Minute Workout

This super simple seven-minute workout consists of 11 exercises done for 30 seconds each with a 10-second transition between them. You can perform one round for a quick pick-me-up or keep going for two or three rounds for a more substantial workout.

1. Jumping Rope - 30 seconds: Start your simple 7-minute workout with 30-seconds of jumping rope (or jumping jacks if you don't have a jump rope).

2. Push Ups - 30 seconds: Next up is 30 seconds of push ups. You can vary your position to make it easier or harder. If you are just starting, you can do push ups from your knees to make it easier. If you are more advanced, try decline push ups to up the effort.

3. Wall Sits - 30 seconds: Get into position for your 30-second interval of wall sits by sliding down a wall (using an exercise ball if you have one) until your knees are at ninety degrees. Then hold the position as long as you can. If 30-second is too hard, slide up the wall a bit to decrease the effort. If it's too easy, try lifting one leg off the floor.

4. Bicycle Crunch - 30 seconds: The bicycle crunch works the abs and obliques. A study done at San Diego State University compared thirteen common abdominal exercises in an effort to determine the best. Each exercises was ranked for muscle stimulation-measured with EMG-in the rectus abdominis, the external obliques and internal obliques.

5. Air Squats - 30 seconds: Next, do 30-seconds of deep, air squats. The goal is to drop down so your thighs are parallel with the ground. Keep your arms out in front of you, keep your back straight and keep your butt back. Drop down and left up for 30-seconds. Start slowly to be sure you have the proper form. As you perfect your form, you can increase the pace of your squats.

6. Step Ups - 30 seconds: Using a step, a bench or a sturdy chair, step up and down for the next round of 30-seconds. You can add hand weights if it's too easy, or you can increase the size of the step, or increase your pace.

7. Triceps Dip - 30 seconds: Using a sturdy chair, a bench or other object, perform as many triceps dips as you can for 30-seconds. To make it easier, keep your feet on the floor, to make it harder, elevate your feet.

8. Walking Lunge - 30 seconds: Perform a walking lunge for 30 seconds. You can take a few paces forward and then return or you can stay in one pace and lunge out and step back to your starting position, alternating sides as you go.

9. Plank - 30 seconds: Get into a front plank position as pictured and hold it for 30 seconds. If this is too easy you can alternate lifting one leg, and if it's too difficult, you can make it easier by holding the position from your hands rather than from your elbows.

10. Tuck Jump - 30 seconds: You can do a full tuck jump (and grab your knees in air), or just a basic squat jump depending on your fitness level. Jump only as high as you feel you can confidently land the jump - it may be a couple feet or just a couple of inches-the idea is to get a little bit of air between your feet and the floor.

11. Side Plank (each side) - 30 seconds: Finish up the routine with 30-seconds of side plank. Be sure to do both sides. This makes a quick workout when you don't have much time or space. You can also add more rounds if you want a longer workout, or take it easier and make this routine into a warm up . Modify your intensity, your pace and your effort as your fitness level improves.
