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

What’s Included:

- Strength & mobility baseline
- Speed / agility check

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)

Google review of GN Strength & Conditioning by Arina Ferdig★★★★★ "Greg is patient, knowledgeable, and dedicated to his client’s success. I had stalled in my own efforts and he helped me understand what I needed to change.Greatly increased my strength and improved my form. Weight loss is improving too! Very happy."

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."

The GN STRENGTH Method

Training

Focused primarily on resistance training to build strength and muscle. This may take the form of bodyweight workouts, dumbbell workouts at home, or commercial gym workouts using a mix of machines/barbells etc., depending on client's abilities, interests, schedule and equipment available.
Conditioning may be added to a training plan if the client needs to improve cardiovascular health and endurance. It is NOT to be used as a "fat loss" strategy.
Beginners and those who have not trained consistently in the past year or more, will see great results starting at 2-3 strength sessions per week.
Keys to success: focus on good technique, consistency, and resisting the urge to jump on the internet and incorporating that dumb shit into GN Strength's carefully designed program.

Diet

Diet plans are customized to maximize the clients' success, with a focus on fat loss, weight gain, or fuel-for-performance.
Diets are strategically paired with the training program to maximize strength and muscle, while reducing fat.
Equally spaced meals, high protein, lower fat, and enough carbs to fuel workouts and daily activity.
Keys to success: Macro tracking, incorporating our key habits, and resisting the urge to jump on the internet and incorporating that dumb shit into GN Strength's carefully designed program.

Habits

Consistent actions done over time become habits, which then become part of our character. While we want to "build better habits", what we are committing to is a laser-like focus on key daily actions.
Identifying and working on the appropriate actions/habits for you will lay the strong foundation for your continued progress.
Meal planning and batch cooking are actions that creates of habit of eating healthy (and breaks the habit of eating fast food)
Stress reduction techniques are actions that create the habit of recovering from training faster and prevents us from "over-indulging" so frequently.
Keys to success: Choose actions/habits that are moderately challenging, but obtainable. And don't let setbacks derail your entire program (because it will happen to everyone at some point!)

GN Strength FAQs

Can I train if I have a limitation/old injury?

Yes. As a professional and experienced trainer, I find exercise variations and movement pattern adjustments to accommodate limitations, so you can make continual progress.

I want to lose 20lbs. Will training with you accomplish this?

Training is a crucial part of a transformation. It builds strength & muscle and keeps you healthy. But training doesn't provide enough calorie expenditure on its own to lose much body fat. That's why a nutrition intervention is needed to reach your goals. My coaching programs specifically combine training and diet to build muscle and shed body fat.

I'm a beginner, what if I can't do these intimidating exercises?

The key is to start with what you are able to do, and progress from there. It doesn't matter if you can bench press 300 lbs. or struggle with 1 push-up, you can build strength and muscle from ANY starting point.

What types of foods can I eat on your Nutrition Program?

Any foods you like to eat. The key is to stay under your daily calorie target, and meet your Macro targets (protein, fat, carbs). There are no "bad foods", only "bad food choices" given the context of your day. Example: having a piece of cake is not bad. Having a piece of cake AFTER you've reached your calorie target would be a bad food choice.

I just want to lose fat, and I don't care about building strength or muscle. Can I do your program?

Restricting calories without some form of exercise will cause muscle LOSS, will not provide the body transformation most would expect, increases long term health problems AND will set you up perfectly for a weight gain "rebound". Whether its exercising with me, or on your own, results are only guaranteed with BOTH training + diet.

Do you coach teenagers?

Yes. I have years of experience coaching the HS athlete as well as the child who just needs to build some confidence in themselves. As long as your child is well into puberty, my training services are perfectly safe and effective. I also offer time slots for families to train together. It's a wonderful opportunity to work hard as a family, encourage each other, and be a good example for them!
