YUP! Mind you this was lunges for people with muscle weakness, balance issues, neurological problems etc. So we had grab bars if we needed and we didn't go as low as physically fit people do but still it was THE WORST she threw at the group. And as a result of her cruel and unusual punishment, I went from my scooter, to a walker and then to a cane in that 2 month period. Stress threw me a bit, but I'm back to a cane and no falls since.Wow for lunges ? I never even thought of that.
The lactic acid build up must have been a killer for you !!!
