Hi Soulo_ridah,
You still have a question about weight lifting. You don’t understand how less weight lifting will make you a better cyclist.
The fysical aspects involved in weight lifting are different than the ones for endurance. If they were the same you could train for the Tour de France by lifting weights and you could be a powerlifter by only riding your bike, right!?
So the impact of weight lifting make the muscles stronger but not better prepared for endurance sport. In other words: there is a point where muscles either become stronger and more explosive of more suited for endurance.
The muscle is divided in three types of fibers. There is type A and Type B. Type A is a pure endurance fiber. It can’t generate a lot of power, but it can generate that low power over and over. Pro cyclists have a lot of these fibers by nature.
Type B is divided in type I and type II fibers. Type II is a very explosive fiber. It can generate extreme power, but only for a very short time (1-45secs). 100m Sprinters and athletes that excel in events like high jump and long jump have a lot of these fibers naturally.
The type I fibers are very interesting. These are the only fibers that can switch. They can be trained to be explosive or to be more endurance focussed.
If you spend more training training with low watts (say zone 2 biketraining) they will develop as great endurance muscles.
If you spend more time training with high watts (say weight training) they will develop as explosive muscles.
What you need to keep in mind is that a sprinter in cycling still needs an enormous amount of endurance. They still need to ride 150-250km to the finish to take their sprint.
A sprinter in cyclist is not a pure sprinter like a 100m sprinter in athletics. Maybe he could be, but in cycling he needs a lot more endurance.
As far as the weight you put on with your weight training. Sprinters do a lot more weight training than GC riders and they have a lot more difficulty getting over the mountains in the pro peloton.
2 Kg less makes the difference of one minute on 1000am. The difference for me between full body weight training or using weights only for the legs and doing bodyweight training for the upper body is around 3 kg.
So when I want to optimize my cycling performance I use weights only for my legs and lower back and do the rest with bodyweight training.
During the build and peak phase of my schedule I go to the gym less often so I an spend more time on the bike and build my endurance engine instead of my explosive engine.
What good is a 400 watt ftp if you can’t use it beause the last 120km’s have left you out of gas!?
Have fun, Coach Robert
