exercises to better my cycling

think it's a good idea for me to do some exercises? maybe lift weights? i'm no skinny climber, more of a sprinter, but not the best. i could use some more power.

all these core exercises sound good too. better power transfer for explosive sprints. oh yeah! not to mention my back isn't what it used to be.

so for february (all 29 days) i will actually workout, do core strength training, and diet. well maybe not diet so much...
