I have done splits similar to that in the past with some nice gains, but the main reason being that it was something different for my body to adapt to.
Many things can work. This could work. Best results will be to stop program hopping and commit to something for a few cycles.
Definitely could. People who just auto-regulate with general splits will end up doing all types of permutations like this and still make progress. Is it ideal? Maybe not. But it can work and will keep people more consistent. It all depends what a person’s goals are.
The split that you have shown will definiately work until it doesn’t work any longer. Know what I mean? Change it up every 6 to 8 weeks and you can’t go wrong.
