The Praevoris 12

12 weeks.
Real data.
Real change.

Not another weight-loss challenge. A 12-week competition scored on what is actually changing in your body: fat lost, muscle built and strength gained. Measured, not guessed.

Why it is different
Most challenges weigh you.
This one measures you.

The scale cannot tell fat from muscle. The Praevoris 12 tracks body composition, strength and real metabolic data through the full Praevoris ecosystem, so the people who actually change win.

01

Measured, not guessed

InBody body-composition scans, tape measurements and strength maxes. Compete and Full Champion add a Week 0 RMR or VO2 Max test.

02

Scored on what matters

Points for body fat lost, muscle gained, pounds lost, inches lost and strength added. Losing muscle never earns you anything.

03

Live all 12 weeks

Your dashboard shows the live leaderboard and your own progress charts the whole way through. You always know where you stand.

Two ways to win
Pick your category.
Chase the title.

You choose one category when you sign up. Each one crowns a league-wide champion who takes home the biggest share of the prize pool.

30% of the pool

Body Composition

For the person rebuilding their body, not just shrinking it.

  • Points for every percent of body fat lost
  • Points for every pound of muscle gained
  • Weight lost counts as a bonus, never against you
30% of the pool

Weight Loss

For the person with real weight to drop, done the right way.

  • Points for every pound lost
  • Points for every percent of body fat lost
  • Muscle gained counts as a bonus, never against you
Bonus points
Every inch and every
pound on the bar counts.
+1per 5 lb

Strength max-out

Set your Week 1 max on squat, bench and deadlift. Every 5 lb you add by the end of the season is a point. You lock in one version of each lift, so it stays apples to apples all 12 weeks.

+1per inch

Tape measure

Chest, waist, hips, arms and thighs. Every inch you lose across them is a point. A measurement that grows from muscle never costs you.

Teams
Go solo, or
rep your gym.

Compete on your own, or join your partner gym's team. Team score is the average points per competitor, not the total, so a 6-person crew can beat a 30-person gym.

  • Teams need at least 6 competitors to qualify
  • Live cross-gym leaderboard all season
  • Winning location takes the belt, plus a celebration day with local press and video coverage

Questions
Before you sign up
Do I need to be in shape to compete?

No. You are scored on how much you change from your own Week 0 baseline, not against anyone else's starting point. Where you start does not matter. What you do in 12 weeks does.

Can I compete if I do not live near a partner gym?

Yes. Remote is built for that. You get the full dashboard, the leaderboard and every check-in, and you train wherever you already train.

Do I have to join a team?

No. You can compete solo for the individual prizes. If you train at a partner gym, you can also join its team and compete for the location belt.

Where are the in-person sessions?

Full Champion sessions run three days a week at Praevoris partner gyms, starting with Champions Gym in Lorton, VA. More locations are being added for the coming season.

What exactly gets measured?

Body composition (weight, body fat and muscle), tape measurements and your strength maxes. Compete and Full Champion add a Week 0 RMR or VO2 Max test, and in-person InBody scans at every check-in.

Where does the prize money come from?

$50 of every entry goes into the prize pool. It is split between the Weight Loss champion, the Body Composition champion, and 2nd and 3rd place overall.

Can I pay over time?

Full Champion can be paid in full or split into 2 or 3 monthly payments. Remote and Compete are paid in full at signup.

Where can I read the full rules?

Every scoring rule, bonus, team requirement and prize split is in the .
