Don't waste money on a health club membership ever again. I used to go in the first week and learn how to use the machines and weights and what part of the body was being worked. The second week, when I was on my own, I would try to remember what I was supposed to do with each piece of equipment, how many reps I should do, etc... and just become confused. By the third week I would stop going. Dan Sheff takes the guess work and the mystery out of it. Dan develops a workout plan for each session and then stands by your side coaching you and giving you direction the entire time. You are never left to try to figure it out for yourself. For me, that has made the difference. I have been going to Dan for four months now and I have not missed a session. I no longer make excuses. Dan is extremely professional and knowledgeable about fitness and nutrition. His evaluation takes into account the reasons you are there before him (health, weight loss, etc..) and he always keeps those goals in mind when working with you. Dan is an extremely positive person so he is a pleasure to be around. I truly believe he cares about me and wants me to be successful! - E. Lewis

After trying other gyms, our entire family worked one-on-one with Dan Sheff at Cosmic Fitness. An hour's worth of conditioning was accomplished in a quality 30 minute workout! Dan is a very positive influence on our entire household. We love his nutrition tips too.

I have been going to Cosmic Fitness for over four years. My training sessions with Dan Sheff have been helpful in more than one way; not only have I noticed a big difference in my physique, but I have also adopted a new way of healthy thinking and living.

I am a partner at a large Buffalo, NY law firm.



I've been a client of Daniel Sheff and Cosmic fitness for approximately 3 years. I work with Dan three times a week when my schedule permits, but never less than twice.



Dan is always "ambitious" for me, which keeps me on my toes and makes it fun. It also makes for real, discernible progress in terms of strength and overall well-being. At the same time, he understands that 66-year-old guys break a bit more easily than 26-year-olds and that they need more attention to things like balance and flexibility. The result is that I progress within the limits of my physiology and almost always feel better for our sessions. I think that my collaboration with Dan has made an important contribution to my overall well-being. I recommend him without hesitation and without reservation.

Simply put, Dan is an excellent personal trainer. Highly and widely knowledgeable, thoughtful, personable, and motivating, I have been working with him for years. He carefully supervises he clients’ workouts; I have never had a gym-related injury of any type. One aspect of his training routines that is important to me is that he adjusts the routines, on short notice when necessary, to fit my sometimes complex physical needs and situations. He also varies the exercises within the routines, which keeps the routines fresh, both physically and mentally. The gym has an excellent variety of cardio equipment available and Dan encourages its use. His availability easily fits my needs. Perhaps most importantly, I have received multiple benefits from Dan’s workouts – I have improved my strength and flexibility, increased muscle mass, decreased body fat, improved my nutrition, and improved my all-around health. It is worth repeating: Dan is an excellent personal trainer!

I came to personal training after years of gym memberships and gradually losing interest in working out. My motivation was low, I had put on extra weight, and I was generally disillusioned with what a fitness plan might be able to do for me. Dan has been a great resource.  The workout regimen I'm on is thoughtful, tailored for me, and he complements it with an extensive knowledge of nutrition and health-related issues. He knows how to push me physically while at the same time being supportive of my current abilities. There's no "gym rat" attitude here- Dan is a supportive presence who cares about what's going on in my life and how it impacts my involvement in a fitness regimen. Plus, I'm seeing results: I have more energy during the day, have lost weight and put on muscle, my clothes fit better, and I'm sleeping well. I'm looking forward to continually setting new goals with Dan's help. If you need more structure to your workouts or are just plain curious about what personal training might do for you, give Dan a call!

Dan is an excellent personal trainer. He helped me train for and pass my law enforcement physical fitness test. I worked with Dan three times per week for approximately nine months before having to relocate from Buffalo in connection with my job. In addition to the comprehensive, constantly evolving physical training program Dan developed for me, he also gave me a thorough nutritional plan to follow. I had never worked with a trainer before Dan, and I was working out on my own almost every day for nearly ten years. In just nine months with Dan, I achieved more than I did in ten years of working out on my own. I lost over twenty pounds of fat and gained lean muscle mass. If you are looking for a knowledgeable, reasonably-priced trainer who will help you achieve noticeable results, I highly recommend you give Dan a call.

Dan rocks! He is fun, dedicated and very competent........he varies my routine and keeps me motivated. I am in much better shape, mostly due to Dan. He gives nutritional advice if needed. Sarah G. (71 years young).

Dan Sheff has been my personal trainer for two and a half years. Throughout those years, he has offered unending support, encouragement, and genuine interest in the personal goals I have set for myself. I consider him a mentor more than a trainer, and I appreciate the level of commitment he shows to me and the rest of his clients.



As a busy health care professional, it would be easy for me to put exercise on the bottom of my list of priorities. However, Dan’s gentle reminders, quiet encouragement, and willingness to accommodate my busy schedule does not allow for this self-defeating behavior. He inspires me to continue on my path to a healthy lifestyle.



Regarding priorities, Dan always makes me feel like I am his number one priority during our training sessions; I appreciate that about him as well. He focuses intently on me and on the exercise I am performing, and he encourages my feedback. He then uses my feedback to adjust the routine accordingly. As a result, our sessions feel like a true partnership…where we work together toward a common goal. He does not allow me to stray from my goal, nor does he allow himself to be pulled away by outside distractions like phone calls, text messaging, etc. I know he values me and our time together; I too value each session.



Therefore, Dan's level of professionalism and commitment to his clients are second to none. I have to agree with his slogan for Cosmic Fitness; he is truly “reshaping” my “universe…one workout at a time.”

I started working out and was happy to find that not only did I get the benefit of a great trainer but advice on diet and overall wellness. Dan Shef is a gifted individual that can keep the foucs and make traing as fun as possible. If you're thinking of a personal trainer give Dan a call. You won't be sorry.

I have been working out with Dan of Cosmic Fitness for year,having reached that age where the belly grows and the fitness wanes I had reached a turning point. I was never a gym person or an athlete. But this Gym and Dan in particular has kept me in amazing shape. I am constantly told I look like I am in My 30's when I am actually just 9 months shy of 50. As an actor my physical prowess on stage is the best its been. Despite the stress of a bad economy and daily life I always leave the gym and Dan feeling better about myself and the world. Dan is knowledgeable, caring and firm. The weekly appointments are what keeps me on track, with obvious results. Dan is just a really great guy. Is personal training an investment? You bet, but with the stress relief, the shape I am in, the lowering of the blood pressure, the Self Esteem... its well worth it.

If you are looking for a personal trainer; I highly recommend Dan Sheff. Not only is he incredibly knowledgeable regarding physical fitness, he is also a terrific source for information regarding diet and nutrition. But let’s face it, what is all that knowledge without professionalism, a great personality, and a personable nature? Dan has all that going for him as well. As he trains you, he will push you to be your best, and he does so in such a non-threatening way. He remains focused on you throughout the session, always checking your form and offering encouragement. He is interested in your feedback throughout the session, and he will adjust according to your comfort level. Working with him feels like a true partnership, and his enthusiasm and love for physical fitness and self-improvement is both appreciated and inspiring. Truly, if you want out of this world personal training sessions, then Dan Sheff from Cosmic Fitness LLC is the trainer for you!

"I started working out with Dan a few years ago at the insistence of a friend. I never realized the experience would be so rewarding. Dan has a gift of quiet encouragement and has been able to convince me to perform workouts I didn't think were possible. I was hit by a car last year and Dan helped me through those challenges and as a result of his regimen I have regained my strength. I now am in the process of becoming a Border Patrol agent, and with his confidence in me I am ready!"
