Spinervals Competition Series 33.0: The Pain Cave DVD

This is a challenging workout that will put you in the pain cave after about 20 minutes or so. It is not boring at all, and the 50 minute workout goes by very quickly. I have a spinning bike and have found the spinervals to be as good as if not better than any spinning class that I have taken. It can be hard to motivate yourself to workout alone, but these DVDs have really helped me. I highly recommend this and all of the spinervals. They also have a "Runervals" series that I will try when I get a treadmill at home.

This item is a great hour on the bike. You will not get bored and it is not too repetitive.

Great workout--I am training for a mountain biking trip in the mountains in Chile and I feel that this series of videos will help me get ready. These cycling drills presented make sense in how to push yourself more and more to get the results on the bike outdoors.
