After about a year layoff, I decided to get back into the gym and hit it. When I hopped onto the leg extension machine and began cranking out reps, I began to notice that, although as far as I could tell, I was exerting the same amount of effort with each leg, my right leg seemed to be "burning" more than my left, and getting exhausted more than the left. When I hopped over to the leg press for the second leg of the superset, I got the same thing. It felt as though I was exerting more effort with the right leg, as it was burning more and fatiguing more quickly than the left. Now, two days after the workout my legs are sore, of course, but the right is more so. What is more likely? Did my right leg somehow become weaker than the left during the layoff and therefore working harder to keep up? Or am I unconsciously exerting more effort with the right for some reason without knowing it? Anyone else experience this? Any insight is appreciated. Thanks guys.
