Join Cody for $20 a month and access more than 2,500 workout videos to establish an at-home yoga practice, challenge your strength, and up your endurance with HIIT and cardio exercises!

Don’t get us wrong, HIIT workouts are awesome. But for those of us who get knee or wrist pain pretty easily, the high-impact jumps and/or mountain climbers often included in HIIT core workouts can leave us scrambling for a comfortable modification. With 100 percent supine (on your back) exercises, this Corefit workout is low in impact while still high in intensity.

The instructors alternate between 15-second static exercises and 30-second active exercises to build midsection strength and get your heart rate up. Remember: Breaks are your friend. Listen to your body, take a little rest, and jump back in anytime. Trust us, you’re going to want to make it to the end of the video for a rejuvenating full-body stretch. Grab a mat, lie on your back, and press play to get started.
