In the Starting Strength method, in the first session the lifter learns to squat, press and deadlift, with women working up to 3 sets of 5 with a weight which is just beginning to slow the bar down. In the second session they'll squat again with a slightly heavier weight, learn the bench press and the powerclean.
With squats, typically in the first session we focus on getting the movement right in the hips, this means "knees out" and "hip drive", ie using the glutes and hamstrings to get the weight up. Once they have that down, in the second or later sessions we look at the grip and upper back. We use the low-bar back squat, which means the bar sits just below the spine of the scapula and on top of the posterior deltoids. People will tend to bend their wrists and let the weight rest on it, which is fine with the 20kg empty bar, but less than ideal with 100kg. In this video, you can see that we're trying to get her to straighten her wrists and pull the bar down into her back.
Caitlin spends a bit too long thinking about all this, and it's hard to hold the bar there for a whole minute. We may have started the weight a bit high for her, we'll just add a smaller amount next time and in a week or two it'll sort itself out.
Bench press is a bit simpler, keep your shoulders back, pick a point on the ceiling directly above you, lower the bar down and press it up, reset shoulders if necessary.
The powerclean like all quick lifts comes from the hips. It's the rapid hip extension that gets the weight up. But people will want to use their arms to get it up, in this respect good upper body strength actually makes learning the powerclean harder. We were a bit hurried at the end of the session so didn't have the time to stop Caitlin trying to row the weight up. That's alright, the weight will go up, and at some point be too much for her to heave up, so she'll have to use her hips.
Some say it takes years to learn barbell movements. In personal training courses squats are described as an "advanced" exercise, not sure what that makes cleans and snatches. The basics can be learned in ten minutes, or a few sessions at worst, it's a lifetime to master.
Caitlin expressed surprise that after the first warmup sets her soreness from last time was gone. This is common, if you wait for the soreness of the first session to go away it could be most of a week, too long. Just ignore it, come in and lift anyway, you'll feel better soon.
She was also surprised that squatting 30 and 35kg felt so much easier than just two days ago.
"Yes, you're stronger."
"In just two days?"
"The first adaptations are not growing new muscles, but learning to use the muscles you've already got, and learning the movement."
She also reports a ferocious appetite after lifting. This is normal, eat plenty of good food.
