What can I do to strengthen my knee joints? Every time I start doing cardio to burn off more fat, after about 1-2 weeks my knees just start falling apart, and I have to wait 1-3 weeks for them to heal. One time I even had to wait 1-2 months for my left knee.
Lately I've been doing 30 sets of 1 minute of jump roping, with 1 minute of rest between sets. I've been doing it on concrete, but I wear good tennis shoes. The only other place I have to jump rope would be in my yard on the grass, but I feel like I would hit the rope or catch it on the grass or something.
I just don't understand why I keep having so much trouble with my knee joints. I'm 23 years old, and never had problems with my knees while playing soccer in high school. I feel like the amount of cardio we did during practice was about the same as what I try to do now.
Is this just a normal thing that happens as you age? Am I just going to have to settle for doing less? Because this seems ridiculous. I really don't get why my knees can't take even a half hour of cardio 4-5 days a week.
I tried eating a ridiculous amount of fat and fish oil pills, and while it does seem to help my knees heal slightly faster, it did not solve the problem.
I'm at a loss for why I can't seem to do the amounts of cardio I see suggested everywhere, so if anyone has any idea what my knees' problem is, or what I can do about it, I'll love you forever for helping me to get my abs cut lol.
