How to perform Db Single Leg Romanian Deadlift RDL:
braced - ipsilateral (db same hand as working leg): hold onto something for balance. Breathe and hold about 70% of breath, brace your core like you are about to get punched in your belly and only release breath out when you are close to the top on your way back. Always maintain core tight. You can perform with db on the opposite hand as working hand (contralateral) whichever you prefer. Rear leg is locked in extension. Lock your lats – arms used only to hold the db (think of arms being ropes with hooks). Chins tucked in – think like holding an orange with your chins. Breathe and hold about 70% of breath, brace your core like you are about to get punched in your belly and only release breath out when you are close to the top on your way back. Repeat the same for each rep. Treat each rep important, be patient and focus on your form. Maintain core tight. Stiff spine. Pelvic floor in neutral position. Spine and neck in neutral position. Don’t round your back. Don’t hyperextend your head/neck to see yourself in the mirror. Don’t hyperextend your back on your lockout at the top. Try to come up with your body moving like a unit. This is a hinge movement, so think of moving your butt back like pushing a door shut with your butt or like someone behind you pulling your hips back with a rope. Push butt as hard as you can and when they can’t go any further come back up. There is a little knee flexion to make it more glutes and less hamstring. You don’t need to go down to the floor and have an excessive range of motion, if you do is more lower back than glutes. So the db goes normally just below knees. If you want to bias more hamstring than you can have a more straight leg and go more lower.
