Now that Im on winter break 1500+ miles from my bike I'm trying to limit my fitness loses. Im going to do a little bit of running but Im taking some time off completly to let my legs refresh. But, Im joining a gym for the month Im here so what would everyone suggest to focus on my legs. Any of that plyometric type activities? I would like to increase my explosive power, i.e. I cant really jump out of the saddle and take off as much as I would like. Should I do squats or stick to machines? Any help would be appreciated.
