I’m 44 and about a stone overweight. I run & swim twice a week but I keep getting injured when I run (I’ve run for years) so Ive started to use the weights machines at the gym as I’ve read they peer women should do strength training, though I really have no idea what I’m doing! Im doing arm and leg machines in like three or four sets of 5 reps at a time and im lifting as much as i can (not a lot at this stage!!). Thing is, i dont feel like im exercising because im not out of breath and sweaty! I normally come off the running machine completely recked. My arms & legs are certainly sore after, but im not getting that runners high im used to. I’m just questioning whether this is the right move to keep me fit at my age?
