I start with a set of just the bar - except deadlifts, where I start with the bar plus the smallest full-size plates (in my gym that's 5kg each). Then I do typically two more sets midway between bar and working weight, at 3 reps and 2 reps each. So, for example, my deadlifts might be 5x30kg, 3x40kg, 2x50kg, then 5x60kg or whatever. I find the 5, 3, 2, scheme is enough to prepare my body and my brain for the heavier weight, for now. I'm not doing *that* heavy* yet. I am not waiting between warm-up sets much, 30-90 seconds. I do SL 3 days a week, and I'm also working on a pull-up program those same 3 days a week. 2-3 times a week, I run about 30mins with the Zombies, Run! app. BUT - I'm not on a cut; if I were, I would only be lifting, and probably not with as much volume as SL. I'm definitely noticing results. Feeling everything tighten up. Nothing "popping" yet, but, like I said, i'm not on a cut right now so it's all a bit covered in residual fat. The only con I see is if you're on a cut. Then it might be a bit too much volume for a steady progression. Aside from that, it's a well-designed program that'll help you build a great base. I was a bit concerned about doing Squat and DL the same days, but, what I've found is that, whichever workout I do two of that week, I do squats first one of the days and after the other major lift the other day. (I.e., DL first or Bench first one day, the Squat first, the other.) Not sure if that's "modifying the program", but it works for me at this stage. I get to push hardest on the first lift while I'm fresh, so each major lift gets one day a week where it's the focus. Some folks prefer Starting Strength - they prefer the more dynamic "power clean" work, and I believe the sets are 3x5 instead of 5x5, iirc. A bit less volume, so easier to recover from. If you do attempt it while on a cut (i.e., a diet to lose weight), keep your protein intake high, and your overall calories as high as you can and still lose inches (or cm) off your waist. DON'T go by the scale, because you'll be building muscle, and your tape measure will be a better tracker than the scale. Finally, do warm up, unless you're one of those 20yearolds who're invincible. 3-7 mins (max) of rowing machine or treadmill or jumping jacks or whatever gets your heart pumping, then a couple minutes of dynamic stretching/mobility work on any areas you need to limber up (I do a little foam rolling then something like the Agile 8, but I'm older so I need more limbering). Doing some mobility work first will really help with your form. But even just doing some bodyweight squats, or arm swings, will help. This is, of course, IMHO. IANAC. YMMV. BBQ.
