Is it too much to do weight training along with cycling? i ride around 30 miles a day 5-6 x week at about 90-100rpms in the summer. It has slowed down significantly now in the winter, but i still do the trainer. I try to do a lot of interval training on the trainer cause Im not getting as many miles in. I also started going to a gym to get some upper body strength which i dont have. My legs are pretty muscular and I dont want to overdo it. It makes no sense to me to do leg presses when you do cycling cause your just reworking the quads. Right? Plus, with cycling you are getting the aerobic workout in addition to strengthening your legs.Should I do different machines? I use the nautilus machines at my gym. Thanks a lot.
