If one has difficulty mastering a given move in the beginning due to strength and/or flexibility deficits (e.g. with SLE/PE1), is it proper to linger on a particular time/set scheme until proper form is achieved before increasing the time?
For example, with Arch Body Holds, I've found that 12sec is a happy medium where I can push myself towards the movement ideals the entire time while also getting a decent volume in. When I've gone further in the time progressions, I've found the my form falls even shorter from ideal. I've decided to hang out at 5X12sec for several weeks to consolidate my form before moving forward. Is this appropriate?
