Yeah, I'm thinking about schedule. I have mostly done a 3/week schedule. I tried 4/week a while back, and got pretty burned out, but there were several factors, including increasing frequency of some lifts. I have had a 4-workout schedule, so one cycle might go m-w-sa-m, and the next w-sa-m-w. My schedule makes 4/wk a bit difficult. Wed is always available, Sat is usually, but I have to work one every few weeks. Monday I'm on call less often than other weekdays, so M-W-Sa usually works out well, with occasional adjustments for work, or for the effects of a bad night on call the night before. If I do 4, I want to be sure to have 2 off days together before the DL day. I used to do M-W-Th-Sa, but there is no 2-day break there. Tu-W-F-Sa might work, but there would be more frequent work interruptions. I've been happy with Sq and DL every 10 days or so, with assistance work for both of them staggered half-way in between. Bench has gotten a heavy day and a medium day each 10 day cycle, and that has gone well.
For a 3-day schedule, what would you think of DL/off/Sq+bench+chins/off/DL assist+OHP+row/off/off?
Our gym is a tin shack in the jungle. We have oly barbells and about 400 or 450 pounds of weight, plate loaded dumbbells that we can load up to maybe 120. There's a multi-station cable machine that is broken, but replacement cables have come, so when someone gets the time to work on it, it will be back. It's good for cable rows, facepulls, etc. I don't use it for anything else. There's a rumor that Santa is bringing a set of bands this way. We have a bench press bench and an old, not very strong rack. It's OK for me, but I wouldn't suggest you use it! So pretty much everything I need for the basics. See this link
for a video I made a few months ago of our gym, and the station where we live.
I haven't had any major injuries, but I've had a few periods of time when back soreness put me off lifting to some degree, usually a week or two off, then a few weeks without full squat or DL, sometimes just doing rack pulls, or only single-leg work. It is not progressive. I've also corrected some habits at work that were making it worse. It never hurts to lift, only nagging soreness later.
