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!
Make sure you get your leg muscle stretches in! It's not a workout but I have a messed up knee too and it's only ever gotten better and stayed better after stretching for extended periods of time.
