So all this time I've been under the impression that being in the gym burns calories, more weight on the bar burns more calories, and thus a higher volume and higher frequency is best for not being skinnyfat
But now I'm starting to realise that any 5x5 program like SL or SS is actually building muscle, which burns more calories AT REST. So effectively, instead of burning a shitload of calories (which actually isn't all that many) in the gym every day, you build muscles so you can burn a shitload of calories when you're NOT in the gym.
Kind of like investing in shares
