As a member of both the Erin Phelan FitFam and Peleton, I will tell you this: Peleton caters to the masses and workouts can be effective but are often bland and uninspiring. With Erin's workouts there is so much variety, you never do the same workout twice, there are lots of compound moves and even with light weights I feel challenged. Erin knows us personally, and cares about us.
