The reason I put this on my list is to challenge myself to try something new. It's easy to get into a bit of a fitness rut and do the same thing every day. I've always wanted to try the RPM classes at the gym, but was worried about how intense it would be and whether I would be survive.
Recently I've been doing my 12 week challenge at the gym, and one of the things I've appreciated the most is the variety in our group training sessions every Thursday night. We had a taste of the RPM class, and I found I really enjoyed it, thus the decision was made. It was time for RPM.
