Kick Out Sit — first steps

Decision

Which should you choose?

The Barbell Straight Leg Deadlift lets you load the heaviest weights and progress in small, steady jumps. The Kick Out Sit needs no equipment and scales through leverage, tempo and reps. If your gym has both options, neither is a wrong choice: pick the one that feels strongest through a full range, and swap after 6 to 8 weeks to keep the hamstrings adapting.
