1 TM - 10 - 1 - 20 - 30

Build up to a training max of the deadlift, 1 repetition, as heavy as form allows, in 15 minutes.

Then 10 reps, 1 more heavy single, then 20 and 30 with a minimum of 5 minutes rest between.

(10 reps about 75% of TM)
(20 reps about 65%)
(30 reps about 55-60% of TM)

Be safe with the weights rather than overconfident. Bracing Sequence through and through.
