I've been lifting free weights three times a week since the end of February. I've also lifted on and off for the last four years (mostly off). I mean to stick with it this time. The weight lifting is part of an overall plan to lose body fat and have some strength for sports (tennis, volleyball, soccer).
This morning, I did a new exercise--concentration curls (sitting, legs spread apart, free hand on one knee, holding dumbbell with other hand with the elbow of that arm resting against the inner thigh). First set was 12 reps and I barely could finish the last one. I did eight the second set; the second-to-last one was hard and the last one I had to really struggle and it seemed to take forever to complete it. I could only do six the last set and again, I struggled to complete the last two (I mean grunting and yelling, etc.)
Shortly after, I felt discomfort in my biceps--I guess what they call the "burn." This is the first time I've ever felt this after doing any weight-lifting. 1) This is normal, right? I should feel this in all my muscles that I work? 2) Did I accomplish nothing in all the times I've lifted weights in the past and didn't feel this burn?
Thanks.
