I would do whichever sport I'd be most competitive in and where I see the most potential for improvement as well. But that might not be why YOU do sports. I could see why you like both sports. Powerlifting is probably a sport where you can improve hugely over time though. Do not know whether the same is true for deca.
I fully understand that view and thats probably part of the reason why powerlifting is so appealing to me. I believe I have greater potential in powerlifting/strongman or that kind of event, compard to other sports. But due to my height, I have to keep a high bw to compete in these and tbh I dont like the feel of my body anymore. Its to bulky, stiff and unathletic.
Im also considering the fact that I have a tiny daughter now, and I want to be able to play with her, without getting winded or breaking something due to my size.
I know that I wont be able to succeed in decathlon. Im to old and not explosive enough by nature. But it will improve my athleticism and Ill be able to do alot of different sports on the side, play ball, do parkour and stuff.
Bottim line, Ive probably decided to go for the loose weight, keep lifting and start jumping/sprinting again plan. It just seems more prudent right now.
