If your goal is to develop strong, lean, sculpted legs, here’s some good news: You don’t need expensive equipment to do it. In fact, all you need is a little bit of space, a positive mindset and your own body weight. This high-intensity interval training (HIIT) leg workout will leave you feeling the burn and a little breathless. As always, be sure to listen to your body and rest as needed. To get the full effect of the workout, however, you must be willing to challenge yourself.

To begin the workout, take five minutes to warm up by incorporating dynamic movements such as jogging, high knees, butt kicks, karaoke, walking lunges and high kicks. These exercises will help warm up the muscles of the legs and potentially reduce your risk of injury.

After your warm-up, this workout consists of two 10-minute circuits. Perform each exercise for 30 seconds, moving quickly from one exercise to the next. The goal is to complete as many repetitions as possible in each 30-second segment (you can download a timer app on your phone that will beep to signal it’s time to change exercises). After completing the first circuit for five rounds, move to the second circuit and complete five rounds. Remember to listen to your body and rest as needed. When you finish the final round, cool down by walking for a couple of minutes combined with static stretching exercises.

Here are a few things to keep in mind: Don’t hesitate to modify the workout to suit your fitness level. If five rounds seem too challenging at first, start out by completing two to three rounds and work your way up to five. As for the exercises, if jumping is outside of your personal limits, you may remove the jumping portions and replace them with a lower-impact movement, such as marching in place. And finally, because this workout involves a lot of squatting a lunging, take caution if you have any issues with your knees.
