plenty of reasons not to join a gym. if youre into running or cycling id always rather run or cycle in the open air than run on a treadmill etc. no way would i pay to run or cycle indoors!!
While I prefer running outside, the treadmill does have some advantages: the weather, it’s dark when I get up, it’s good for intervals/speed work… but most of all it’s next to work – I commute to the gym before the rush hour starts, get my run in before work, shower, and it’s done and dusted by 9am.
I do also use the weights, which I don’t have at home, and I used to go to classes although at my current office I don’t have time.
That said – there are a lot of people who turn up for a month or two, then disappear. We seem to be hitting the post-xmas / pre-easter peak at the moment, there’re lot more people in the gym at 7:30 than there were before xmas… but it won’t last. So OP I’d recommend giving it a go, it can definitely make a positive difference to your biking if you take it seriously, but make sure you’ve read the contract and know when to cancel (if need be).
And enjoy the hotties 8)
