No equipment cardio...that is also easy on the knees?

My knees are finally starting to feel some soreness after my workouts, so I'm going to put a stop to jogging for awhile but still want some cardio I can do outside of the gym. Any ideas?

 

Heavy bag!

 

skipping rope

 

shadow box, air squats, burpees, pushups

you can get a jump rope for about two dollars

 

box jumps (u dont really need a box) burpees are great mix them with push ups. Jumping jacks with squats are good as well.

 

So your knees are pretty much fine and this is just preventative yeah?

 

No equipment at all? Shadowboxing, imaginary jumprope (much easier to not catch the rope on your feet), burpees, supersets of squats and pushup variations with kicking and punching, burpees mixed with shadowboxing...

 

Jumping jacks, skipping, jogging on the spot, mountain climbers, running on grass or rubberised tracks, swimming, cycling, rowing, cross trainer and burpees without the jump.

 

Hill Sprints; the angle of the running stride means there is significantly less impact on the knees than when performing LISS.

 

As others have said, shadowboxing is one of the easiest types of cardio on the joints. I have a rheumatic type of arthritis in all of my joints, but I can still shadowbox no matter how bad they feel. I also sometimes do BJJ drills at a moderate speed. Shadow BJJ, if you will.

I also like to row, but that requires equipment.
