Take 20 or so minutes and find a 1RM deadlift in a sumo stance. This is a wider stance with feet outside of your grip width. You’ll be in a more upright position compared with a conventional stance which puts less strain on the lower back.
For the metcon, do a full Tabata (8 rounds of 20 seconds work, 10 seconds rest) for each movement. Count total reps across all three movements for one final score.
