I’ll bet you didn’t know that if you have a flight of stairs anywhere near you, you basically have a full gym. You can run up, walk down and repeat for interval sprints and mix it up with lunges, jumps, and toe-taps. Do 30 second bursts and you’ll be burning! If you want to tone your upper body muscles simultaneously you can even add incline and decline pushups on the stairs as well!
On the floor in a high plank position, bring knees in 1 at a time (like you’re leaning forward climbing a mountain) to your chest and back to the floor. I like to do these for 30 seconds at a moderate pace, focusing on the stretch and full range of motion, then stand up and go immediately go into high knees at maximum effort for 30 seconds. Do that a few times. Oh, you’ll know it’s working!
I like to make cardio out of bodyweight exercises. 2 birds with 1 stone.
Cardio is NOT only a leg thing. By definition, it’s a heart thing, anyways, but people associate it with running only all too often.
Try: 10 squats, 10 pushups, 10 jumping jacks, 10 crunches, 10 supermans.
Repeat this 3 times in a row and all with as little rest as possible.
