My husband's favorite exercise activity is to use his recumbent bike for 45 minutes after getting home from work on a daily basis. The pedals and resistance can be adjusted. He uses multiple resistant levels during the session to get the most bang for his buck. He has lost over 75 lbs. and consistently kept it off for over 8 years now. He also likes that he is sitting up on the bike with his hands free, so he can listen to music, watch a tv show, or play a video game to pass the time. He wouldn't have it any other way because he gets his stress levels down and keeps his weight right were he wants it to be. These pedal straps keep his feet in place and can be installed in less than 2 minutes. They are easily adjustable for larger or smaller feet.
