The Week's Tally
What changed in the last seven days. Pure rolling — refreshes every weigh-in.
The Standings
Ranked by pace — fastest body-fat loss wins the race. Fast horses up top.
The Trail
Every weigh-in, plotted. Toggle cowboys to focus the view — the y-axis re-fits to whoever's left on the trail.
Weight (lb)
Mass on the scale.
Body Fat % BUCKLE OR BUST
The one that matters. Cross the gold line and the buckle is yours.
BMI
For the bookkeeping.
Under the Iron
The buckle rewards muscled hunks with single-digit body fat — not skinny bitches. Weight down is only worth a damn if the numbers on the bar keep going up. Post your 5-rep max after every heavy day.
Squat 5RM
Legs. Base of the whole operation.
Bench 5RM
Push. Chest, shoulders, tris.
Deadlift 5RM
Pull. Whole posterior chain.
