I've been riding bikes since 1966, always owned medium level road bikes.
You DON'T need to pull upwards on the pedals when you use clip pedals. The clips only hold your feet on the pedals, they don't tell you how to peddle.
Those stationary bikes your see in high end gyms are useless toys. The seats are crap wide, the crank arms too short, the handlebars too close to the seat, the the "resistance" just means inertia.
