OK here is what I do now Tuesday, Thursday and Saturday or Sunday depending on work schedule.
2 sets 10 reps
Squat - alternating days Leg Press
Dead lift - Alternating days straight leg
Leg curl
Bench (flat)
Inline DB
Chins- Smith machine
Rows or Lat pull down
Shoulder Press
Delt (rear)
Lateral Raise
Shrugs
Bis 3 sets 2 DB 1 Cable
Tris 3sets 1 DB 2 Nose Crushers

Abs or Cardio depending how I feel
3 days a week is perfect for HST. Here's what I'd pick out of those lifts:
Session A
Squat
Bench
Shoulder Press
Chins
Nose Crushers (I'd prefer dips)
Abs
Session B
Deadlift
Bench
Shoulder Press
Rows
Nose Crushers
Calves
Alternate A & B:
Week 1 - Tues A, Thurs B, Sat/Sun A
Week 2 - Tues B, Thurs A, Sat/Sun B
You'll need to test your 15RM (rep max), 10RM, and 5RM for each of those exercises. After you have your RMs, take 9 - 14 days off from any physical exertion so that your muscles can decondition. This is important so that your sessions will be most productive for muscle growth from day 1.
The first 2 weeks you do 15 reps for every lift
Weeks 3 & 4, you do 10 reps for every lift
Weeks 5 & 6, you do 5 reps for every lift
Weeks 7 & 8, your choice: a) keep doing 5 reps and try to push for new, higher rep maxes on your lifts; b) do negatives or drop sets; or c) drop to even lower rep scheme like 3 reps and work up to a 3RM
The default set selection is 1 set for 15s, 2 sets for 10s, 3 sets for 5s
There are 6 sessions for each 2 week rep scheme. Here are the loads for the 2 week series:
Session 1 - 75% of RM
Session 2 - 80% of RM
Session 3 - 85% of RM
Session 4 - 90% of RM
Session 5 - 95% of RM
Session 6 - 100% of RM
If you have a lift, like the nose crushers where breaking the increments down that small is not practical, you can double up and just go 80% - 80% - 90% - 90% - 100% - 100%
I think I've covered the basics of the default version of HST (some call it the vanilla method). Like I said before, HST can be customized infinitely, so if something above doesn't work for you adjustments can be made. But the principles of HST - progressive load, frequency (3x a week), time-under-tension, and strategic deconditioning are the key to maximize your growth. Hope this helps!
