Among other things yeah. If like that style of training do a classic 5x5 like madcow or Bill Starr template. Thib put out this recently also.
if going to perservere with SL then once you stall(which will happen soon) move on straight away to something off Tnation pref with a good amount of metabolic work and varying intensity -this will build you energy in turn should help lift mood
Yeah as above, dont worry about this. Doubly so if 40+ …Bit like saying “hmm if go for a run every morning, dont want to accidentally end up in the Olympics next summer”
