Every 3 mins for 12 mins do:
12 Alternating double DB Reverse Lunges standing on a plate (6/6)
8 L/8 R double DB Staggered Stance Deadlifts, pick load

Lunges: Slow, controlled movement. Aim is for the knee to lightly touch the floor.
DL: go as far down as mobility allows, good posture comes first!
