Thanks! I actually quite like beltless, but I haven't done regular deadlifts beltless for a long time (those are paused deads, so there is a 4 count pause in the middle of the weak point of the concentric - resulting in one of the most horrible exercises to do).
In theory, bletless places a greater stress on the core. I don't know if I'm massively weaker beltess, but definitely slower (which definitely makes me weaker on these paused ones because of the extra time under tension).
Judging from today's session, beltless paused + farmers definitely rapes the core!
