All good answers so far, so I will summarize.
Squat: quads, glutes mostly, really works the entire body.
Bench: chest, some anterior deltoid/tris
Row: Traps, some lat, bi
RDL: Low back, hamstring
Shoulder Press: medial deltoid, some tri (anterior delt if db held in front)
Lat Pulldown: Lats, some trap, bi
The PRIME MOVER is being worked once during the above workout: Quads, Chest, Trap, Hamstring, Deltoids, Lats. PLUS you're doing plyos that week as well so that's more leg work.
You will always feel an exercise in your weakest muscle group. This is why it is so difficult to feel anything in your glutes, especially for runners. The glutes are your strongest muscle. If you really want to feel these then you'll have to lift very heavy and deep as the glutes are activated mostly during high intensity contractions and out of hip flexion. Yes a step up would be a great alternative.
For Squats go to at least parallel. Ideally go as low as you can go. Do Not Let Weight Dictate Form. Let your form dictate your weight. If you cannot complete proper form, ie: complete range of motion in a controlled fashion, then the weight is too heavy. Pay especially close attention to these during the Squat, RDL, and any pulling motions (Row).
You will not hypertrophy. You will not hypertrophy. You will not hypertrophy. You will not hypertrophy. You will not hypertrophy.
I'm going to get a shirt made to give out to girls/women and male distance runners that says "Lifting Weights Will Not Make Me Swoooooooold!"
On the back of the shirt will be a top 5 list:
1. You are not producing enough testosterone to add large amounts of muscle.
2. You are producing too much cortisol to build ANYTHING.
3. Your body is in a continual state of muscle breakdown and repair.
4. You will NEVER build muscle as long as you are running an hour a day.
5. Unless you're eating 200g of protein a day you will not gain significant muscle mass.
For variation here is a list of other exercises:
1. Squat, Lunge, Step Up
2. Bench, Fly, Incline/Decline variations
3. DB Row, Chest supported Row, Seated Row, T-Bar Row
4. RDL, Deadlift *don't do deadlift after/before back exercise, don't do deadlift and squat in the same workout*, glute/ham raise, hyperextension, Straight Leg Deadlift, Good-morning
5. Shoulder Press, front raise, lateral raise, y-raise, incline varations, upright row, scarecrow, L-raise
6. Lat Pulldown, pullups, straight arm pulldown, pullover, grip width variations
....and that is only the beginning, there are 1000s of ways to do an exercise or hit a muscle
