Personal training at Redefine Fitness is fully customized around the individual. Each client receives a weekly training plan, tailored workouts, and one-on-one guidance from certified trainers who live the lifestyle they coach. The sessions take place in a private, focused environment designed to support confidence, consistency, and long-term results. Ideal for beginners, those returning after injury or time off, and individuals looking to break through plateaus.
Training at Redefine Fitness is tailored entirely to you. Every program is customized to your goals, fitness level, and lifestyle, and your weekly plan evolves as you get stronger. All sessions take place in a private setting where you can focus without distractions, and every trainer is a certified professional who genuinely practices what they teach. Instead of following a generic routine, you receive expert-guided coaching that improves your form, builds confidence, and keeps you progressing safely and consistently.
This approach works well for beginners who want structure, individuals returning after time off or injury, and anyone who has hit a plateau and needs more personalized direction. Because every exercise and progression is designed around your abilities, most clients notice improvements in strength, mobility, posture, confidence, energy levels, and overall body composition. The combination of expert guidance, private training, and a plan that adapts weekly helps create long-term consistency and meaningful results, regardless of your starting point.
Your trainer builds your plan after a detailed assessment of your fitness level, movement patterns, mobility, goals, lifestyle, and any challenges or limitations you may have. This evaluation shapes how each session is structured and how your weekly plan progresses. The goal is to design a program that fits your life, supports safe training, and helps you move better each week. If you have past injuries or physical limitations, your workouts are modified to support proper movement and pain-free progression.
Most clients train two to three times per week, although your coach will suggest an ideal schedule during your consultation based on your goals and recovery needs. Accountability is built into the process: your trainer tracks your progress, adjusts your plan weekly, guides your technique, and checks in regularly to help you stay consistent. Clients often find that this structure alone is one of the biggest reasons they finally stick to a routine.
Yes, Redefine Fitness offers a private and focused training environment that eliminates the distractions of a crowded gym. It’s comfortable, supportive, and ideal for building confidence—especially if you prefer a quieter space or are just getting back into fitness. Getting started is simple: visit the Redefine Fitness website and fill out the consultation or contact form, and a trainer will reach out to schedule your initial assessment. After your evaluation, your personalized program is created and your sessions begin. You can also call the studio directly if you prefer to speak with a coach right away.
Trustindex verifies that the original source of the review is Google. Had a 2 week experience in Redefine when over from UK. We were given a great welcome and encouragement. Targeted personal training for knee improvement was very professionally delivered - but always with a personal touch and empathy. Well done Kyle and Hannah! And thanks!Posted on Brian BrianTrustindex verifies that the original source of the review is Google. Kyle And Kolja Are The Best Trainers I highly recommend themPosted on Jameson KonenTrustindex verifies that the original source of the review is Google. Redefine Fitness in Stony Brook is hands down one of the best gyms I’ve ever been to. The atmosphere is welcoming, the equipment is top-notch, and the whole place is always clean and well-organized. But what really makes it stand out is the staff. Shoutout to Both Kyle and Kolja. They are incredibly knowledgeable and genuinely care about helping you reach your goals. Whether it's tweaking your form, answering questions, or just offering that extra bit of motivation, they’re always professional and approachable. They know what they're doing, and they make you feel confident and supported.Posted on Chris RuedTrustindex verifies that the original source of the review is Google. awesome trainers! everyones great!!Posted on Sarah ArrietaTrustindex verifies that the original source of the review is Google. I previously posted a positive review for my former Redefine trainer, Amanda. Now that she is in management and I have a new trainer, Hanna, it’s time I sang her praises! I continue to be proud of myself for making the commitment to working out. This level of exercise and strength training has been the best gift I could ever give myself. I feel strong, sure-footed, and healthy. I couldn’t do it though without Hanna! She might be young but she’s wise and sensible. We have such a nice rapport that I never hesitate to tell her if I’ve got some little issue troubling me because I know she will find a way to adapt my workouts accordingly. This is wonderful because it means that even if I’m not feeling 100% for some reason, most recently from jet lag, I can still get a good workout in. Most days I feel great and we get to it! Hanna pushes me, just the right amount. And all the other trainers are so friendly, my little successes are often met with cheers from the entire staff. It’s really sweet, like all of Redefine is cheering for my success! With this level of support from Hanna and the Redefine family, I know I will be a client for what I hope will be a very long, healthy life!Posted on Lisa BlakeTrustindex verifies that the original source of the review is Google. Been training here for over 2yrs and it’s been great. The trainers are knowledgeable and polite they’ve helped me work through past injuries. And the new faculty is nice and well equipped.Posted on V R
