I managed to put on 13 kilo’s in 18 months (49>62Kg),
You weighed 49 kilos??? That is tiny! That’s also quite an alarming weight increase.
I used to be very fit and actuve in my 20s. Swam, cycled, played footie and went gym 3 times a week. Din’t put on a bean. Was very strong for my weight though. Weighed a smidge over 8 stone.
Now, I do far less, drink and care less bout it, yet am bigger and stronger. 9st 10lbs on Sunday. 😯
Swimming’s what’s given me more strength and bulk. That and middle age fast approaching.
Be warned; put on loads of bulk that’s not natural for your body, and when you’re in your 40s, unless you train loads all the time, it will all sag, turn to fayt and be unsightly excess bulk that will be hard to shift.
Best to be fit, agile and healthy, than try to look like Rambo.
