I hear you on the back and heart condition, and fully understand the change in philosophy when it comes to wellness vs bodybuilding. The bodybuilding lifestyle is about as healthy as being a fat guy playing video games living on little caesars lifestyle. I jacked my back about a year and a half ago and I actually died last year on the 4th. Stress related seizure, the doc said. One minute I was at the pool with my daughter and some friends, next thing I woke up in the neuro ICU with a tube in my throat, my arms strapped down, and puking and fighting to get away and find Q.
Shit happens.
Thing is, you can't do a callout and not follow through. I bet if you went through one cycle of lifts and posted them plunk would be impressed, maybe even unable to do them. But who fucking cares? Even if he whoops your ass you still manned up and did it and it gives you a goal. If you beat him, you get a win and a chance at humility.
Bran whooped me in a fat-off that we had, and I guarantee by the time I was done working on myself I was beyond most of the fgts on the AAS board and content with my accomplishments, not so much my appearance.
Either way...
