I'm not sure if this is the right forum for this or not.
I just started consistently riding this year. I've noticed when I try to get out of the saddle on tough hills that my legs feel weak. I can power up them while sitting but can't seem to stand. If I'm at a traffic light, I can stand to get thru the light quickly with no problem. Is this just a training issue, do I need to strengthen my legs more with squats? I do them now but no weights, just lots of reps.
