Step 1 Pre-Test your Standing Toe Touch (don't warm up), if unable to comfortably touch your toes than make an imaginary or real spot on your shins for post test
Step 2 "The corrective exercises"/Reset
Exercise 1-Single Leg Hooked Bridge:
Exercise 2-Active leg lowering
With one leg resting against table for support with a knee straight, brace core with hands firmly pressing into floor and actively lower other leg to foam roller (or any object), then raise again; keep both knees straight throughout the motion and ensure normal breath control
Step 3: Re-Integrate
Squat down with heels slightly raised on book, barbell plate or 2x4,etc. Grab unto a stool or trash can and lift hips up (and back) and straighten your knees while holding unto stool. If unable to lock out knees than pick a taller object to hold unto instead of stool. Straighten back and rise (pic3). Squat back down and put hands back on stool,etc to repeat. Repeat 10 times.
Step 4: Post-Test your Standing Toe Touch. Better? Let us know in the comments!
NOW YOUR READY TO DEADLIFT!
Step 5: Retrain- The Deadlift
This will also make sure you can still touch your toes and move better in over 20 minutes from when you Post-Tested (although steps 1-4 may need to be repeated until you always 'own it'). It is vital to let the body know its new range of motion and tension that you have. The Retraining Step improves 'motor memory adherence' just like practicing a new language or technique improves retention of that skill.
Maintain contact with PVC (or broomstick) at back of head, spine in between shoulder blades and buttocks (sacrum). Bend forward, hinging at hips ensuring the PVC maintains contact with all three points throughout, especially the butt. Start with only a small amount of bend in the knees. Imagine their is a wall about a foot behind you and you only want your butt to touch it (practice ~1 foot away from wall!).
Ensuring better movement allows for better performance and strength. Get better with the standing toe touch and watch your deadlift max, running pace, and Crossfit durability improve with it.
