"Helen" is typically done with a 400m run. If you have access to a C2, attempt to row rather than run. If you keep the intensity up your grip never gets a rest!
Begin with this slight variation of the Burgener Warm Up:
1) Down and up: Feet in Jumping position, hook grip, drop hips slightly keep torso erect and stand tall 2) Down and up with shoulders: same movement as Step #1 with an added shoulder shrug 3) Down and up with shoulders and elbows high and outside: same movement as Step #2 with barbell now traveling to mid chest 4) Muscle snatch: same movement as Step #3 with the barbell ending in the overhead position (*DO NOT re-bend the knees *DO NOT over rotate the shoulders *Keep barbell overhead in center of mass) 5) Transition from Jumping to Landing position: With barbell pressed overhead, transition from Jumping to Landing position => Just like C) 6) Transition from Jumping position to Overhead squat: Simply increase the range of motion of Step #5 and quickly drop into a full overhead squat from the top of your muscle snatch 7) Hang Power Snatch
Complete 3 to 5 sets of each individual movement before progressing to the next.
