If you haven't been dedicated this summer it's not too late to get some conditioning for the winter.
I am changing my program from my summer program of biking five days a week, to three days and putting more time in the weight room, rock climbing, uphill running and some tennis.
Rock climbing for overall and core strength, flexibility, agility.
Tennis for movement, reflexes, hip strength, lateral movement.
Uphill running for hampstring, glutes, lower back, aerobics.
Weight room, for abs, lower back, core, upper body.
