Personal Training & Functional Strength in Woodland Hills
where your fitness is individualized–never generalized
At Impact One Fitness in Woodland Hills, we specialize in Functional Strength Training tailored to your goals, lifestyle, and fitness level. Functional strength is more than what you can lift in the gym; it translates to better everyday movement and wellbeing. That’s why true strength goes beyond numbers or appearance—it’s about moving better, feeling stronger, and living healthier.
Our functional strength training programs are designed to improve balance, mobility, and coordination while building lean muscle, boosting metabolism, strengthening joints, and increasing bone density. Most importantly, they give you the confidence to handle both the demands of daily life and the activities you love outside the gym.
Whether you’re just beginning your fitness journey or ready to push to the next level, our elite personal trainers create customized strength programs and provide nutrition support to keep you motivated, consistent, and on track.
We offer a variety of personal training options to fit your needs:
-
1-on-1 Private Training – full focus on you, your goals, and proper technique
-
2-on-1 Semi-Private Training – your own individualized program, sharing the session with one other client we pair you with
-
4-on-1 Small Group Training – enjoy small group energy, motivation and accountability
-
Nutrition Coaching – build balanced, sustainable eating habits that support your results
-
Our Client App – schedule sessions, follow your program, log at-home workouts, see your progress photos and manage billing in one place
Who we work with
Our clients range from their 30s to their 70s, with most in their 40s, 50s and 60s, and they come to us from Woodland Hills, Tarzana, Encino, Calabasas, West Hills and across the West Valley. Many have trained with us for years. They come to us to:
• Build muscle and real strength, at any starting point
• Lose body fat and change their body composition for good
• Keep their muscle while losing weight on a GLP-1 medication like Ozempic, Wegovy, Mounjaro or Zepbound
• Move better, with more mobility, flexibility, balance and better posture
• Stay strong and capable as they age, including protecting bone density
• Train around back pain, old injuries or physical limitations
• Get back in shape after time off, a life change or having a baby
Our clients choose Impact One because they want it done right: an experienced coach who knows their name, their history and their goals, a program built only for them, and a private studio where every session is by appointment.
With private, semi-private and small group options, there's a way to train with us that fits your goals and your budget.
How getting started works
1. Reach out. Fill out our contact form or call us at (818) 485-2010.
2. Talk with Micah. A short phone conversation about your goals, what training with us is like, and whether we're the right fit for you.
3. Come in for an evaluation. We assess how you move, your history and your goals, then recommend the right training option.
4. Start your program. Private 1-on-1, semi-private 2-on-1, or small group 4-on-1, plus nutrition coaching and our client app.
Every membership starts with a trial period, so you can be sure we're the right fit before you settle in.

Frequently asked questions
Where are you located?
20300 Ventura Blvd, Suite 110, Woodland Hills, CA 91364. We train by appointment Monday through Friday, 6:30am to 7:30pm, and Saturday, 6:30am to 12:30pm.
What training options do you offer?
Small group 4-on-1 is our most accessible option. You follow a well-rounded program designed for the group, and your coach adjusts each workout to you.
Semi-private 2-on-1 gives you your own individualized program. You share the session with one other client we pair you with, so you don't need to bring a partner.
Private 1-on-1 gives you your own individualized program and your coach's full attention, for anyone who needs the extra attention or simply wants it.
Every client also gets nutrition support and our client app for scheduling, workouts, progress tracking and billing.
How much does personal training cost?
Training with us is an investment in your health, and there's more than one way to make it. Small group 4-on-1 is our most accessible option. Semi-private and private training cost more because you get a program built only for you. Pricing depends on the option and how often you train, so we walk you through it in a short call once we understand what you're after.
Do I have to commit long-term?
Our memberships are 4-month or 12-month agreements, and every one starts with a paid trial period: your first 2 weeks on a 4-month agreement, or your first month on a 12-month agreement. Instead of a single free session, you get to really train with us, see how we work, and make sure the program works for you. If it's not the right fit for any reason, you can cancel during the trial and we'll refund what you haven't used.
Why a trial period instead of a free session?
One session can't show you much. A few weeks of real training lets you see that we're professional, that we do what we say we'll do, and that the program fits you. It also means everyone who trains here has chosen to be here, and that's a big part of the culture at our studio.
Do I need to be in shape before I start?
No. We work with complete beginners and experienced lifters, and every program starts from where you are today.
Can you work with injuries or chronic pain?
Yes. Our trainers specialize in corrective exercise and build programs that work around past injuries and limitations. We'll always recommend checking with your doctor when it's appropriate.
Is strength training safe for people over 50?
Yes, when it's coached properly. Strength training is one of the best things you can do to protect muscle, bone density and balance as you age, and it's a big part of what we do.
I'm taking a GLP-1 medication. Can you help?
Yes, and it's one of our specialties. Weight lost on GLP-1 medications can include muscle as well as fat. Strength training and enough protein are the best tools for holding on to that muscle. We build your program and nutrition coaching around that goal, and we're glad to work alongside your doctor.
Who are the trainers?
Impact One is co-owned by Micah Roberts (ISSA CPT, PN1, 25+ years coaching) and Ali Shields (NASM CPT, 20+ years coaching). Meet the full team on our Meet the Trainers page.
