Jazzercise

First day back at Jazzercise.  Already had planned on doing the low-intensity but was surprised how tired my legs felt after the second routine.  Upper body felt fine but didn't think I was this weak.  Need to work on this.  But it was good to be out among people, and will continue to be good for me so although it's a little hard, I'll keep going instead of asking for a break.  I wonder if its the meds or if my body really got this weak.
