Westside-type training works well… no need to work up to a 1RM, working up to a 2 or 3RM would be better for a 1B.
But that is only one approach.
A template I like includes…
A. Explosive activation drill (jumps, throws, sprints, prowler sprints)
B. Explosive lifting (speed sets on a big compound lift, olympic lifts, high pulls, push press, etc.)
C. Heavy movement (same or related to B)
D1 - D2. Assistance work with one exercise in the 6-8 and the other in the 10-12 rep range… often using antagonist pairings
E1 - E2. Smaller isolation exercises one in the 8-10 and the other in the 10-12 reange
But a 1B should try to accelerate the weight regardless of the movement
