That's right I'm dissing the most famous split.
In my opinion it is less effective than pairing
The reason I think this is that when you do a push pull split almost all your lifts will be puny except the first one. If you know what I mean. On the other split I mentioned each set can be heavy weight. Your muscles won't be fatigued. I'm going to leave it at that. I already wrote a post like this about 5 months ago but I thought I'd just let the new guys hear my opinion.
