What a nice gift from your husband!
I just thought of something you could do for the jumps and hoovers...
I have heard of people jumping off the treadmill and doing squats, weights, pushups, or whatever. Then they jump back onto the treadmill for more cardio...
So I wonder if you might want to do something like that for the jumps; perhaps step off the treadmill and do body-weight pulse squats or squat jumps trying to match Cathe's tempo.
Maybe one day you'll get a spinning bike. Besides, I agree - can't have too many Cathe workouts! LOL!
