In my home we are fortunate enough to have a rowing machine which I bought about 15 yrs ago. At the time I thought that it would be cheaper and more convenient than a gym membership. Funnily enough despite its age it isn’t yet worn out! Like much home gym equipment it has served its time storage/clothing support.
Anyway I have unearthed it and started to use it for some morning aerobic exercise. I don’t want to risk injury by running every day. I do get some tightness in my hamstrings which puzzles me as many people do exercises to strengthen their hamstrings and get tight quads, which I don’t. So I wondered which muscles are used by running and rowing, same or different?
