Make sure to point the bike towards the TV ok really...

1) loosen roller adjustment so it won't obstruct the bike going on the trainer
2) Put the rear axle between the two cups and tighten the cups onto each side evenly
3) Tighten roller back up 2 turns after contacting wheel

As recommended above, get a large fan from Target or something. You will sweat!!! I never realized how well moving air cooled you until I rode a trainer.
