I really did not try and overdo it at the Y, but my back has been horrible for 3 days now. I hope it isnt a kidney stone.....it feels not quite like I hurt my back. Getting a wee bit better so I did some pushups which was fine.
For lower leg strength....walk some sidehills. Doesnt take long before you feel it and a ditch will work.
What you do today is important, you are trading a day in the rest of your life for it.
