How to Create a Snatch Training

Hi,
Im training snatches once a week, Im a beginner (my max is 80kg/180lb) and Im not sure how to create a training unit. Should I do some OHS before?

My current snatch training:

  1. Full body warm-up (15min)
  2. Hanged Snatch (+ one OHS after last rep in each set)
    5x20 5x30
    4x35 4x40
    3x45 3x50
  3. Full Snatch + OHS
    1x60 1x65 1x70
  4. Full Snatch
    4X1X75
  5. High pulls with previous weight
    • not sure how many reps

… thanks for any advice
