12-Minute HIIT Workout (No Equipment Needed!)

This full body HIIT workout will torch calories and get you sweaty and out of breath in no time. It takes only 12 minutes to do and requires zero equipment. Try it when you’re traveling and don’t have access to a gym!

For this workout, all you’ll need is an interval timer or timer app, and your own bodyweight. Set your interval timer to 18 rounds of 10-second and 30-second intervals, then prepare to rest on the 10 second intervals and work really, really hard on the 30 second ones. Go through three rounds of the following exercises:

Start in a lunge position with your knees touching or almost touching the floor. Jump up explosively and switch legs so that your rear leg is in the front and front leg is in the rear. Repeat with the other leg, then jump back up, but this time, land in a squat position. Repeat sequence with speed and control.

Start in a push-up position with your shoulders directly over your hands. Tighten your abs, glutes, and thighs, then lower yourself down so that your chest touches the floor. Push back up, then bring one knee towards the opposite hand. Lower back down into a push up, then repeat on the opposite side.

Stand in a side lunge position with one leg bent parallel to the floor and the other leg straight to the side. Jump up explosively as you switch legs. Now the previously straight leg will be bent and the previously bent leg will be straight to the other side. Try and keep your core tight and stay as low as possible as you switch sides as fast as you can.

Start in a squat position with your hands touching the floor. Jump up explosively as you reach your arms up as high as you can. Land back in a squat and repeat.

Stand with your feet about shoulder-width apart with a medicine ball or other obstacle to one side. Jump over the medicine ball to one side, drop down and do a burpee, then immediately jump back to the starting place and do another burpee. Repeat.

Make it harder: Increase the difficulty by adding an obstacle to jump over. The higher the obstacle, the more difficult the jumps will become.

Start in a downward dog position. Jump your feet up as far as possible and land on one side, pushing up through your shoulders as you do so. Immediately jump to other side and repeat.
