I've had knee injuries to deal with so I avoid jumping jacks too. If they come up in workouts I just do what Tania in Shaun T's T25 program does as a modification. It's just stepping out with one leg at a time while moving your arms up and down like a normal jack. I'm not sure if that description makes sense, but it gives you the range of motion and gets the blood flowing without the trouble of jumping :-). I'm glad to see that you've come back. We all need some breaks at times. Hope the next month is a great one for you!
