Not sure if I can recommend this suggestion, because for me exactly the opposite worked out fine.

I never used fitness crap lying around my home regularly but once I started paying for a gym membership there was no way I would just stay at home and pay for nothing.

In other words I used the sunken cost fallacy for my benefit.

Once I was more advanced it wasn't the money I spent on my membership that kept me going but knowing that I'll actually get weaker if I started to only go 2 times a week instead of keeping up my 3 times a week routine. So every time I didn't visit my full 3 days a week it felt like I essentially wasted a few of my last trips to the gym because I wouldn't see any progress and at the very best just keep my performance at a plateau.

I trained quite hard for 1,5 years and missed maybe 4 training sessions, until a knee injury from squatting with too much weight coupled with moving to a new location put a stop to my training days.
