The below is a post from Strengthcoach.com, and there is an extended segment on the principles and execution of the Chop and Lift on the upcoming DVD, Training = Rehab, Rehab = Training.
* Do you, or can one, perform these in both spilt stance and regular stance?
Yes, these Chop and Lift patterns can be done in supine, tall or half kneeling, standing symmetrical (squat), standing asymmetrical (lunge), standing 1-leg (SLS/hurdle step).
*Is the typical progression in these moves to do them kneeling then move to standing?
Yes, but please consider that the kneeling moves are corrective in nature, and the standing-style moves are closer to conditioning.
*Any specific tips/cues you like?
Pack the neck
Only use the arms
*Can you share how you progress these (chops and lifts) or do you like staying in that kneeling position > keeping the legs out of the movement.
The progressions are to mimic the weakest link in training the FMS or SFMA. If one of the Big 3 is dysfunctional, removing the contribution of the knees, ankles, and hips can cull out these compensators to train the core if warranted.
*Also what qualifiers do you use to move someone from the kneeling position to standing.
A 3 on the FMS.
*What other progressions a have you used or experimented with in the chop and lift pattern?
Supine for knee pain folks.
Qualifying for the Chop and Lift for static stability before allowing the dynamic stability/movement of the bar.
Bar to Rope to Band to Medball
*Have you/ do you use med balls and what did you find effective and not?
Very effective in longer term lower quarter surgeries where the movement with the upper quarter warrants progression, but the lower quarter does not warrant loading.
Very hard to do without a lot of medballs or someone else to retrieve the ball.
