Whether you're crashing with your family or hosting them during the holidays, you'll probably be squeezing a ton of people into a small house. Unfortunately, "not being in your own element or having very little space can deter you from squeezing in a sweat," says BJ Gaddour, C.S.C.S., creator of -- Men's Health StreamFIT.
But you can do this move -- a complete lower-body and core blaster -- without even picking your feet up off the floor. "You need only a few square feet of space to perform the hip turn split squat," Gaddour says.
"Instead of alternating your feet, as you do in a traditional split squat, you use your core to help change your stance, by switching the direction you're facing," he explains. Not only do you target your glutes, quads, and hamstrings -- some of the largest muscles in your body that burn the most calories when you work them -- but you also hit your abs.
"And pivoting between each rep challenges your balance, stability, and coordination, which will help you burn even more calories" Gaddour says.
Need to squeeze in a super-fast sweat? Try performing this move in short, explosive bursts of 20 to 30 seconds to send your heart rate through the roof.
