It can also be good cross training to get your ass out of the saddle, when you need some active rest. And don’t forget the general lean body mass and bone density benefits. By learning to resistance train appropriately, one develops lifetime physical competencies that benefit your general musculoskeletal health and function as you age.
There might be some women who could benefit from some increased general strength, particularly upper body. There may be some men or women who lack the torso stability to efficiently transfer power to the pedals. But to determine this, we need to evaluate that individual’s weaknesses off and on the bike and see what’s going on. We should never just blindly apply a stock resistance training program; first evaluate the athlete! Does s/he really have some deficits that might be addressed with off the bike training? This type of evaluation is RARELY available to cyclists who want to resistance train in the off- season. And every fall, an army of well-intentioned cyclists line up for the leg extension machine with their basic program from a book or pay big bucks to hop on the PowerPlate and have no idea how what they are doing relates to their on-bike performance.
So what are you waiting for? Give me a shout and let’s figure out what your needs are, so you can stop wasting time in the gym and start doing something beneficial for yourself—on the bike and for your health.
