I’m 63yo rph with a crazy work schedule. I’m new to cycling but have been working out for a long time. I’m using a Kickr bike trainer and love it. I haven’t done any outdoors riding in 15 yrs and don’t see any reason to start now that I can train indoors anytime I want to. The Systm app has become a bit of a rabbit hole for me. There’s so much good info.
