Recently, I've gotten really into doing low-impact cardio workouts on YouTube. Even if you love your plyometric exercises such as burpees, star jumps, and jumping jacks, there's a place in your fitness routine for low-impact cardio. When those jumpy, intense moves are off the table — whether because you're injured, tired, a beginner, coming back to working out after a hiatus, or just don't have the space — low-impact workouts are a great alternative.

And if you think these low-impact cardio workouts are sweat-free, you'll be in for a rude awakening. All "low impact" means is that you always have some part of your body (usually a foot) on the floor, which makes the moves less jarring on the joints. though they're often confused, low impact doesn't mean low intensity; you can still get your heart pounding when doing low-impact cardio moves. You just won't be getting your knees pounding too.

Try one of the following low-impact cardio workout videos — all from our award-winning YouTube channel, PS Fit — to see for yourself; you're guaranteed to spike your heart rate and save your floorboards, while being gentle on your joints.
