Posted under 'Exercise' but posting here too for traffic.
I'm mid-40s and healthy weight though not particularly fit. I go through phases of regular exercise but don't do anything high impact (rickety joints, and just recovering from hip bursitis). I occasionally throw my back out and the doctor recommended core strengthening exercises, including weights.
So last week I did a weights class after a long time. It was tough but I felt really good afterwards...until my triceps started getting sore and stiff. This was not normal post-workout soreness (that the rest of my body did feel!), it was quite severe pain and my triceps felt rock hard, not in a good way. I was unable to extend my arms fully for 4 days, though it felt a bit better on the 5th day.
Question for you lovely MNers is, should I do this class again? Is this "my body getting stronger" and "I have to push through the pain"? Or am I potentially causing some sort of damage to my body?
