I don't really "train", I just like to ride my bike. But when it's nasty weather outside I do my "telly training". I pop my rollers in front of the telly and while the program is on I spin (50/19'ish) and when the ads come on I stick it up near or in top gear and push until the ads end. Usually for around an hour.No science involved but the silly name makes me chuckle and keeps the old legs going. Anyone else have thier own non scientific way of doing indoor riding?
