When comparing the F1 Assessment video (with the woman) and the one on the main F1 page, they are using different levels of momentum in the "up" portion. The woman seems to use little-to-no momentum, while the guy uses a decent amount.
If I attempt the deck squat as in the assessment, I can't even do one. But with a little momentum, I can do 5-10. Should I start with some momentum and work up to no momentum for mastery of the deck squat?
