The 2026 Summer Shred Challenge is wrapped, and this year gave us exactly what we hoped for: measurable progress, better habits, and a clearer picture of what actually moves body composition over six focused weeks.

From April 5 through May 17, members trained, logged daily nutrition and lifestyle habits, completed InBody scans, and stayed accountable through the leaderboard. It was not about perfection. It was about stacking enough good choices to create visible change.

The headline numbers

For final scoring, 17 participants had enough body-composition data to be included. Across that eligible group, the results were strong:

  • 139.2 lb total body weight lost
  • 128.5 lb total fat mass lost
  • 51.6 total body-fat percentage points reduced
  • 3.0 body-fat percentage points reduced per participant on average
  • 16 of 17 eligible participants improved body-fat percentage
  • Group muscle mass stayed nearly flat, averaging a 0.1 lb change per participant

What worked

The biggest lesson was simple: the habits mattered. The average compliance rate was 54.1%, which means the group did not need to be perfect to make progress. Members who kept showing up, logging habits, training consistently, and staying engaged tended to move the needle.

The strongest compliance scores came from Monique Verdin at 92.5%, Cara Jones at 79.3%, Dharamesh Patel at 77.2%, Jessica Kwong at 76.6%, and Maria Salas at 75.6%.

Compliance and outcomes

We also compared compliance bands against body-composition outcomes. This is not a lab study, and it does not prove causation, but the trend lined up with what we see as coaches: people who consistently hit the basics are usually the people who create the most reliable change.

Those basics were not complicated. Protein. Fiber. Sleep. Less processed food. Strength training. Class attendance. Bodybuilding accessories. Progress scans. Small things done repeatedly.

How we kept scoring fair

One important update this year was how we handled body-composition scoring. InBody scans are useful, but they can fluctuate based on hydration, carbohydrate intake, glycogen, and scan timing. Body weight is measured directly, while skeletal muscle mass, fat mass, and body-fat percentage are model-based estimates.

For final scoring, we reviewed the raw scans and used an adjusted body-fat percentage calculation designed to reduce unrealistic swings. The adjusted score uses body-weight change as the anchor, limits extreme muscle-mass movement, and translates the result back into a body-fat percentage-point change. Members can still see the measurements they entered, but the score is less likely to reward a scan-day artifact.

This keeps the challenge more transparent and more fair, especially when someone comes in depleted, fasted, dehydrated, or unusually hydrated on scan day.

Leaderboard snapshots

The public leaderboard kept the energy high. It gave members a reason to keep checking in, and it made the challenge feel like a team event even when everyone had individual goals.

What we are taking into the next challenge

Next time, we will keep the habit-based structure and the public accountability. We will also be even clearer about scan prep so baseline and final measurements are as consistent as possible.

That means scanning under similar conditions, avoiding extreme dehydration or depletion before a scan, and treating body composition as a trend instead of overreacting to one isolated reading.

The challenge worked because it gave members structure without turning nutrition into a crash diet. Train hard. Eat like an adult. Track the basics. Let the work compound.

Get ready for the next one

If you missed this round, the next Summer Shred is the one to watch. It is built for members who want a focused push, better accountability, and a realistic way to lean out without abandoning strength training.
