Jefferson curls while still on MN/PE1

Hi guys, I am still on PE1 for manna but I’d like to already add Jefferson curls to my workout. What do you think would be the best strategy to incorporate them? Separate from the rest of my workout (same or different day), or including them as additional manna mobility (for example, a single set in addition to the sets of stiff-legged windmills), or perhaps in conjunction with one of the stretch series? Looking for tips and ideas  oh yeah, what would be a reasonable weight to start with?

HI MIchael, simply wait. In case of the tight posterior chain without a decent range of motion acquired on IM1, you can get fewer benefits and more risk of injury.
