I've been using Fitness+ over the holidays. It's quietly impressive.
Right now it's limited by the fact that a) it requires an iPhone and Apple Watch Series 3 or later and b) there are no live classes but the seamless experience leads me to believe that Fitness+ ($80/year) will eventually become a force for
$PTON to reckon with (alongside
other competition), putting downward pressure on Peloton Membership ($40/month and $13/month) growth and the company's goal to reach
100M subscribers.
