The physical training device comprises a moving endless conveyor (10) powered by at least one drive-wheel (15). It is placed horizontally in a stand, with at least one further roller (16). One of the rollers can be removed from under the belt by just slackening belt tension and then sliding the roller along its guides, taking if off, and re-inserting it at a position outside the conveyor. It can in this position act as a support for a bicycle drive wheel. |
