She holds a certification in Pilates mat and apparatus from the Physicalmind Institute.

In the last 10 years Sheri has really been focusing on Pilates as a total body functional conditioning format that combines stretching and strengthening to help you feel great. Pilates works on stabilizing you from the inside out. The stretching always feels great and the strengthening that comes from longer muscles is empowering. Pilates helps to balance the body that often gets misaligned from activities of daily living. While research is still ongoing on Pilates with low back issues, Sheri has found it to be most helpful to many individuals that she has worked with. Recently Sheri has added TRX to her Pilates practice as a further challenge.

Lindsey Della Serra

Lindsey graduated cum laude with a BFA in dance from Mason Gross School of the Arts and is finishing up her Masters in Dance Education at Rutgers University. Born and raised in Cranford, Lindsey has been dancing since the age of 3 and currently teaches dance at Yvette's Dance Studio to students ages 3 years old to adult.

Lindsey completed her extensive Pilates apparatus training program with Polestar Pilates at the Mason Gross School of the Arts, where she worked with clients from ages 12 to 80. Lindsey also taught Pilates mat classes locally where she catered the movement to improve her students' yoga practices.

Lindsey believes that "getting to know our bodies is the greatest gift we can give ourselves. By giving our body the attention it deserves, we can revive our mind, body and soul through movement." She truly wants to help all people be their best self!

Joseph Pilates spoke of his exercises as a way to, "build a sturdy body and sound mind fitted to perform every daily task with ease and perfection as well as to provide tremendous reserve energy?"(Return to Life, 1945). Lindsey feels that "our bodies are our life and everything we do has an affect on us. By learning efficiency of movement with Pilates, tasks will begin to feel easier and energy can be restored. "

Lindsey is available for individual, duet and small group Pilates Reformer and Apparatus instruction.

Kelly Robertson

Kelly graduated cum laude with a BFA in dance from Mason Gross School of the Arts at Rutgers University. It was also at Rutgers where Kelly later completed the internationally renowned rehabilitation based program: Polestar Pilates Comprehensive Training at the top of her class. She is a Pilates Method Alliance (PMA) certified trainer and also completed Comprehensive Pilates Mat Training through the Kane School of Core Integration.

As a former professional dancer and dance teacher to aspiring young dancers, Kelly has experienced a life in union with movement. A severe neck injury in 2002 ended Kelly’s professional dance career, challenging her self-identity and body perception. Her rehabilitation was long, arduous and started Kelly's roundabout journey with Pilates.

After giving birth to her first child, Kelly began studying Pilates, which helped regain her 'core' stability and strength, balance and tone to her muscles, improved her alignment, and most significantly shifted her perception of her body in a positive way.

In 2012, after a hip injury and subsequent surgery it was Pilates that helped Kelly achieve a successful and speedy recovery. Having experienced rehabilitation in two different ways (one with her neck which was difficult and one with her hip which was much more successful), she understands that any work towards positive changes in the body cannot be isolated to the body nor can it be completely dependent on an outside source.

It is Kelly's aspiration to help facilitate successful movement experiences by integrating the 'whole person' (mind, body, spirit) and to be informed by their responses, movement outcomes, unique body structures and fitness goals.

Kelly's work spans all populations including: general fitness, dancers, gymnasts, active older adult and post rehabilitation. Kelly has experience working with varied conditions including: osteoporosis, disc pathologies, stenosis, shoulder and scapulothoracic bursitis, diastasis recti and abdominal hernias, osteoarthritis and rheumatoid arthritis, hip and knee pathologies and colostomies.

In addition to her private Pilates instruction, she is a part-time lecturer teaching Pilates to dance majors at Rutgers University, and was a resident instructor with Cirque du Soleil on their show 'Totem' in New York.

Kelly is available by appointment to teach individual and duo Pilates Reformer and Apparatus instruction at Personal Best.

Kristine Elmore

Kristine Elmore
Kristine Elmore

Kristine is an ACSM certified personal trainer and functional training specialist, group fitness and Spin instructor as well as a NASM corrective exercise and golf fitness specialist.

Just 4 years ago Kristine was 80 lbs heavier and not really feeling good about herself. She was turning 30 years old and saw the youthful days of her athleticism slowly fleeting. She tried everything from diets and supplements to extreme exercise tactics that only lasted for a short period of time because it's hard to keep motivated when you're in constant pain and she wasn't in the condition physically to handle routines that demanding. After a while, the aches and the pain started to out-weight any potential benefit derived from long-term adherence.

She was always athletic as a young girl and grew up playing basketball, baseball, softball, soccer, volleyball, and eventually, tackle football. Right before turning 30 years old, Kristine set out to do things differently. She wanted to become more active, fully enjoy life and challenge herself to be better. A family friend found an all women's tackle football team ( in the tri-state area and she decided to tryout. She became intrigued due to her love of competition and this "new challenge" was just the push she needed to really become serious about her health. That was 4 years ago.

In 2013, Kristine had the great fortune of being selected to play for the Gold Medal winning USA Women's Tackle Football Team. It was the constant encouragement of her teammates and coaches that provided the motivation to get through intense workouts and drills. During this period she learned a lot about herself as well. Consistency became the key fact in her transformation.

After 'retiring' while on top, so to speak, Kristine decided to study for her personal training certification, which she completed in 2014. Her world had changed because of fitness and she wanted the opportunity to share this with others.

Fitness is a love of hers and she is always eager to pursue educational opportunities (she is currently studying to become a ACSM certified inclusive fitness trainer, ACE- orthopedic specialist and a NESTA mixed martial arts conditioning coach).

Kristine believes that external forces drive us all at some point but it is the internal force, the person within, that we need to satisfy first and foremost.
