I have been attending "Strength for Life" classes since December 2015 on the advice of the medical profession.
The classes are small, 10 - 12 people and sometime quite fun. I like the fact that the Gym is small and we "oldies" are not trying to do our "thing" while young and lithe persons are doing their "thing", though on occasions there might be 1 or 2 of the younger generation.
Our trainer, Paula has empathy for our generation and on the whole the exercises are not too strenuous. Some of us are not exactly fit!!
