All the exercise I need I get from working. Even when I played hockey or when I was in the military I was never much for gyms. Managed to always stay strong and fast by just working hard daily.
I was always competitive though, so maybe that was my edge. No one could climb staging as fast as me, always lugged two bags of cement, always sprinted up stairs etc. I’m still in fairly good shape, but I’m no longer trying to out compete anyone.
One thing that always stuck with me growing up in the trades was just how useless a gym rat was at actual work. They worked their muscles in a counterproductive way to actual work, so the skinny guy could actually outwork the muscle guy at moving heavy material up staging like brick and mud.
So there is my bias.
