How Training With GN Strength Works

Step 1 — Athlete Assessment

Every athlete starts with a quick questionnaire and in-person assessment to understand their goals, training experience, and movement quality.

What’s Included:

- Movement screening (squat, hinge, single-leg stability)
- Strength & mobility baseline
- Speed / agility check
- Injury history review

Outcome:
A clear understanding of what the athlete needs to improve, and a recommended training plan.

Step 2 — Training Program

Athletes train in small groups with their individualized program focused on building strength, speed, and resilience.

What Training Includes:

Strength & power development
Speed, agility, and conditioning
Injury prevention (hip, knee, ankle stability)
Progression based on ability and experience

Environment:

Small groups (3–5 athletes)
Coach-led sessions
Individual attention within a team setting

Step 3 — Progress & Development

Athletes are continuously coached, monitored, and progressed to ensure long-term development.

What This Looks Like:

Ongoing coaching and feedback
Metrics driven coaching to avoid guesswork
Adjustments based on performance and season
Focus on consistency and long-term growth

Outcome:
Stronger, faster, more resilient athletes prepared for their sport.

Google review of GN Strength & Conditioning by Amy L★★★★★ "Started working with Greg a year ago to build strength and have someone to help me with my form. As we worked together I added in his nutrition coaching. I've lost 20 pounds and have greatly improved my muscle tone, strength, stamina and balance. Look and feel the best I have in years."

Google review of GN Strength & Conditioning by Hal Broderick★★★★★ "Took my son and his friend to Greg for a workout evaluation and it was great! The boys loved Greg and loved the insight he provided on their lifts and improving technique. Greg put together a great program for them based on their goals and sports they compete in and the workouts have provided great results! Since then he has evaluated their videos and made additional recommendations to continue improving their lifts and technique. Highly recommend Greg!"

Google review of GN Strength & Conditioning by Mark Keady★★★★★ "As a dad-bod in my late 40's, I have had a hard time being motivated to do the work necessary to stave off disease and age. I know that lifting heavy weights is the secret to increased testosterone, better self-confidence, and overall health. But I can never do it alone. Greg and GN Strength was an investment in myself. I spent twelve weeks with Greg, lifting for an hour twice a week. His program puts you on a path to gaining strength every week and noticeable change. I never missed a workout. Not once. My goal was to finally stop being "skinny fat" and put some muscle on my chest, back, and arms. Mission accomplished and I've got the success under my belt to keep going. GN Strength and Conditioning game me the push I needed. If you're a man who's needing the jump start to get yourself back to how you used to be and to take advantage of the last decade or so where you can turn back the clock physically----why not give it a shot? In two weeks, you know you made the right decision."

It depends on your goals:

Youth athletes: 2–3 sessions per week is ideal for improving performance and preventing injuries.
Adults: 1–3 sessions per week can improve strength, mobility, and overall fitness.

Absolutely. I provide guidance on fueling, recovery, and habits that support your training goals—whether that’s peak athletic performance for teens or sustainable health improvements for adults. And as a Certified Nutrition Coach, I can also help with fat-loss and weight-gain goals.
