When I was younger I used to train with my brother. And we would follow a typical bodybuilding split. What I mean by that is that our training days were divided up based on body parts and certain exercises.In other words our workouts might have looked something like this:Day 1 - legs, arms and absDay 2 - glutes, chest and absDay 3 - back, shoulders and absA few things should jump up at you right away. First of all, what does 'legs' mean? Is this quads, hamstrings or calves? Or all three?Apparently abs were really important with bodybuilding and they never require a rest day. And getting huge, or swole as the kids now like to say, was priority numero uno. No one did cardio.A warm-up involved a few light sets under the bar before starting in with the first sets of bench press. There was zero stretching or mobility work. And although we did abs it was mostly to target the rectus abdominis, or six pack. We didn't know or care about the core at all.We took rest days when the gym was closed. Otherwise it was simply rotating through this three day rotation looking to add load to the bar at every workout.Although we now know this to be terrible programming it's surprising what hard work over time will achieve. When Jon went to depot for the RCMP I believe he put some lifting records in the weight-room.But we could have gotten even better results. And a study from a few years ago might have given some clues as to how often we could train certain movements and muscles.What the researchers did was look at muscle damage to the arms and legs after training. They wanted to know if there was a difference in recovery between smaller (arm) and...
