Main Challenge: After each of their first five 100 step-ups, they had to shed the amount of weight corresponding to that particular week in the season. For each of the other four rounds, they had to run a mile before depositing some more weight.
The first contestant that shed all their weight and raised their flag got the one-pound bonus, plus won a $25K home gym...
...and it was Ada!
SUDDEN DEATH WEIGH-IN:
Ada: 179 lbs, seven pounds lost (w/ bonus), 3.78%
Elizabeth: 192 lbs, four pounds lost, 2.04%
Mark: 292 lbs, seven pounds lost, 2.34%
Patrick (needs to have lost at least 11 pounds to definitely avoid elimination): 279 lbs, 12 pounds lost, 4.12%
Frado (needs to have lost at least double digits to avoid elimination): 248 lbs, 15 pounds lost, 5.7%

Brendan: 260 lbs, five pounds lost, 1.89%
