I like to do a squat day and a hip hinge day.
Squat day: Pick between back squats, front squat, split squat, lunges, step ups.
Hip hinge day: pick between deadlift (with a trap/hexagonal bar), single leg dead lift, straight leg deadlift, romanian dead lift.
You can also add any ancillary lifts at the end. Hamstring curls on a physio ball, eccentric heel raise, terminal knee extensions, dumbbell glute bridge, etc. You want to do the compound lifts first and more isolated lifts last.
Also, a little blurb from NSCA Essentials of Strength and Conditioning:
To increase Serum Testosterone by using these methods independently or in various combinations:
-Large muscle group exercises (deadlift, power clean, squats)
-Heavy resistance: (85-95% 1RM)
-Moderate to high volume of exercise, achieved with multiple sets or multiple reps.
-Short rest intervals (30-60 seconds)
To increase GH:
-Use workouts with higher lactate concentrations and associated acid base disruptions; that is, use high intensity (10RM, or heavy resistance) with three sets of each exercise and short (rest peroids).
-Supplement diet with carb and protein before and after workouts.
