Hello everyone I'm new to this site and was hoping someone could help me out. I have been racing Mountainbikes for about 10 years and was wondering if there would be anything to use that might boost my power and muscular endurance.I'm not looking to put on size, just something to help in my strenght gains. I do some lifting during my winter training before the racing season. I usaully start racing during mid March. any info would be helpful.
