400 meter walking lunge
Post time and number of steps.

Notes: This was done at Jennersville Y in the cardio room rather than at the track which would be preferable.  Did not have exact distance so  I did 5.5 laps around the cardio room (each lap is roughly 70m). If I do this anywhere but a track in the future, it is better to count total steps until I reach 400. A good strategy would be to break this up into 20 sets of 20 lunges with 7-10 seconds rest between sets.
