I was running on a treadmill I got for free, but my knee is mess up and I can’t even handle that. I’m looking for a free stationary bike to keep up on my cardio. But what are some effective workouts to do without any equipment? I just recently started with 3 sets of 20 push-ups, 3 sets of 20 lunges, 3 sets of 15 squats, 3 sets of 20 knee to elbow touches. Any input is appreciated!
50 burgers/50 situps. Then 40/40, 30/30, 20/20, 10/10.
You can adjust the intensity based on how you're feeling.
