So after my little foray into some serious hills in the mountains of North Carolina, and a "hill" or two that kicked my butt, I decided to ask the bike mechanic if I had the correct bike to even try to attempt such a feat, given that I would not have the proper mechanical knowledge on my own. A trek 7.7 was a new addition to my family last spring and it was about time to get the free tune-up from the bike store. Being assured by the bike mechanic that I do indeed have some sufficient granny gears to attempt such a feat, I have come to the conclusion that I do indeed need to get some better legs. My current routine for muscle conditioning is a Curves workout, which has been sufficient up to now, but I think I need to do more.What kind of strength training should I be doing in addition to my current routine that won't create extra torque on some sensitive knee issues?
