I'm training to kick butt at the RSC, as I've always been the loser in fitness at school and so on. I'm very much more fit now, but I keep getting muscle strains and soreness even with a proper warm up and cool down. The PTI at my local gym recommends I take a small amount of creatine. I've been reading about this and various sources say it turns you into a brick shit house, which I don't want (i'd have to buy new clothes) so does anyone know if this is supplement is ok to take considering I need to have good cardio fitness, which will be harder if I carry more weight... I'm reall confused!
