Thanks for the suggestion, MarcF. I'm going to get someone to record a video of me deadlifting next week.
This was last Thursday:
Back squat 130x3x5
Bench press 100x3x5
Inverted rows 4 sets of 6 reps
By the way, I'm just listing my "work sets." I go through a series of warmup sets, too. I figure those out using an app called "Starting Strength Warmup" by Steven Pugh.
One thing that I've noticed that makes me cautiously happy: Since I've started lifting in a consistent way, my fragile left shoulder hurts less than it did. It's still weak, and it's clear that my progress on the strict overhead press is going to lag. I anticipated that it would hurt a lot or that I would injure it again, but so far this hasn't happened. In fact, things that used to make it ache a bit, like driving long distances, actually don't seem to bother it as much.
Even more than technique, my main obstacle right now is figuring out how to feed myself consistently, especially at work. There is a cafeteria at my workplace, but that gets expensive. The alternative is to bring a large duffel bag with two or three meals in it. (Some days I am at work for about ten hours.) Can anyone recommend recipes that make large batches that keep well and can just go into a container for lunch later? "Salads" with grains, beans, vegetables, and animal protein are ideal, since they don't even need to be put in the microwave.
