A. Tempo deadlift – 5×3 @ 51X1 tempo (5 sec negative, 1 sec in bottom, eXplode up, 1 sec at top). Increase weight 5-10 lbs (if your max is under 200 lbs), or 10-15 lbs (if your max is 200+ lbs). You should be at about 78% by now. Use an overhand grip as much as possible to work on your grip strength, but if grip is a major issue, switch to a hook grip or mixed grip.
B. Alternating with a partner, resting as needed, for 5 lengths each:
1 length heavy sled push
Weight should be challenging, but you should be able to complete the length without stopping to rest (ideally).
C. 3 max effort sets of body rows (no tempo).
