I’ve also been doing SL 5x5 for the past few months. I like the simplicity of the application calculating your loads for each session. Perfect for beginers!
Last two months i am also including one bootcamp style workout into my regiment, just to spice things up a bit.
I’ve gone keto about a month ago, i did notice feeling weaker for about 3 sessions, and i have noticed some lightheadedness at the latter rounds of heavy squats. Nothing problematic though.
