I only do 3 days a week of Oly lifting and so far it’s worked well for me as a 85kg masters lifter (38yrs old).
This is what I do:
Monday
Snatch max double, then 3-5x2 @ 90% of the days max double (10 total lifts above 90%)
Clean and Jerk max double (2 clns + 1 jerks) then 3-5x2 same as above.
Back Squat 321 x 3 I start at about 85% of max and once I can do 3 sets of 321 I add 5kg and repeat. Once I stall on this I’ll go to 1RM then back off sets.
Belt squats 5x10-12
Wednesday
Either Snatch from blocks or pause snatch + snatch. Work up to 2nd to last set of whatever I hit on Monday. No back offs.
Clean & Jerk - same as above, 2 clns + 1 jerk.
Front squat 1RM, then 3-5x2 @ 90% (10 total lifts)
Friday
Snatch 1RM, then maybe 1 double @ 85% of this max depending on how I feel.
Clean or C&J 1RM (currently only max clean as my jerk is not my weakness) same as above
Back Squat - same as Monday.
Belt squats 5x10-12
I sometimes will work in pulls or sn/cln dl’s at end for 3x3-5 on one of the three days - usually mon (cln) & wed (sn), if I do sn dl’s then I also do pauses off the floor and at the knee.
I do kettlebell circuits on tue/thur so that’s when I get my upper body work in - mainly kb presses, push ups, kb rows.
If I do end up doing upper body in the gym I keep it fairly easy and go more for the pump using mainly machines and Gironda style 6x6 or 8x8 …or I’ll do 5x12 with 45-60s rest., however if you’re new and need mass or more jerk work then I would probably throw in push presses and incline presses, push press + jerk, etc, rows, chins.
