I am recovering from a shoulder injury,I went to the gym yesterday after 2 months of rest and recovery. Felt as if, I no more have the same will power and motivation left in me. I need motivation

Art there any classes at your gym? Sometimes, just getting moving with other people can give you the jump start you need.

we need be more care with our health

I would suggest joining a class, there's less chance you'll walk out till it finishes
