I was torn between this and the WattBike. I'm not an uber cyclist, I like a decent 30-40km during the summer and had a spin bike at home to tick over. But I saw a number of boxers raving about WattBike as mixing up their training and a few footy teams used them during lockdowns when they couldn't get to training.
I'm two weeks into some decent Zwift rides (3 or 4 a week), weight is coming off, fitness improving rapidly (even though my base level is always decent). Really really impressed.
Yep, pricey bits of kit etc, WattBike is about £2k, but I'm going to now ditch my gym membership.
