I'm not a peloton fan... I think there are definitely better ways that someone could spend their money if they wanted to cycle and get fit, but I have some friends that have picked one up over the last few years and they all enjoy it. One of them is a cyclist and rides his road bike, but hates going out in the winter. He tried his bike on the trainer last winter, but didn't enjoy it... not nearly as much as he enjoyed the Peloton. He spent nearly everyday on it last winter and he was a better/stronger cyclist come spring.
As someone that lost a lot of weight, and changed his life around because of cycling, people often ask me what is the secret... I'm not sure what they expect me to tell them. There really is no secret, but the only thing i can really share with them is that they have to find something they enjoy doing. The hardest part about making a lifestyle change to lose weight or get more fit is sticking with it... no matter what you do, it will be hard work. In the beginning, it will be hard to see the gains or any improvement. You'll feel like you're doing work, and not getting anything in return. I think the first 30 days of a new change is the hardest. If people enjoy Peloton and it gets them motivated and moving, that's awesome. I think the commercial accurately portrays how hard it can be to try something new and stick with it.
