Sounds weird, and I think for a lot of people it can create an unhealthy attitude towards sport. Like, kind of the same as eating first and then "working it off" during training. Same here, training not for pleasure but to earn something. For me it’s no problem to pay for a subscription in a fitness app, canceling it is also super easy https://support.madmuscles.com/hc/en-gb/articles/7075931986706-How-can-I-cancel-the-subscription if I don’t like something. And then I just train for fun and benefit, not wanting to get something material in return.
