These are a classic. You might not think much of it, but there’s a reason why it’s still being used in the military. Jumping jacks work different muscles that are often neglected in a running program.
For this exercise you should try to do 60 seconds of jumping jacks with 20 seconds of rest. Repeat this cycle for a total of 15 minutes.

Anyone can do it. Old, young, good knees or bad knees, indoor rowing is a low-impact exercise that is easy on the joints.
A 160-pound person will burn about 250 calories in just 30 minutes of rowing, which is as much, if not more than, what you would burn on the stair climber or the elliptical. (3)
