With the right coaching, I was able to push past my limits. I couldn’t have reached my goals without the guidance and support of an experienced coach.

Founder and Head Coach

Hi, I’m Jared

For years, I thought strength meant doing more — training harder, eating cleaner, sleeping less. I pushed through exhaustion, believing discipline would bring freedom. It didn’t.

When burnout finally forced me to slow down, I started listening. I studied how movement, hormones, rest, and mindset work together — and rebuilt my strength through awareness, not pressure.

Hi, I’m Jared

Every rep is coached — that’s how you get strong without getting hurt.

Nothing gets loaded until your form holds, so this works whether you trained yesterday or not in ten years.

Day 1 to Day 84

All 12 weeks, written before you start — every session and every check-in decided before day one

Pre-Start

Consultation & Onboarding

Fill out our questionnaire and get set up on the Body Bento app. Then, we meet for 30 minutes to discuss your goals. A conversation, not a sales pitch.

Weeks 1–2

Baselines & Basics

Body: We establish your baseline with a movement assessment and food diary. Your custom plan goes live, and we tweak things early to remove any friction.

Weeks 3–4

Forming the Routine

Training and eating stop feeling like a chore and start becoming a habit. We finish month one with a full review against your day-one baseline.

Weeks 5–8

Data-Driven Progression

Momentum takes over. We safely increase your training load and adjust nutrition targets based strictly on your 30-day data trend—never guesswork.

Weeks 9–11

Making It Stick

You take the reins. We teach you how to adjust sessions and manage your meals so your results last long after the 12 weeks are up.

Week 12

The Final Results

A full reassessment of your strength, movement, and body composition. See the complete picture of your hard work, and let's map out what comes next.
