I have been doing some weight training on my whole body since around mid-October. One area of concern is the disparity of strength in my different leg muscles. My hamstring curl weight maximum for both legs is only around 120 pounds at 5-10 reps. However, I can do around 12-15 at 150 for the leg extensions and near 300 pounds 3X10 for the calf raises. Is there any problem with this?? Is this adequate for cycling?
