Naina Bhasin, PhD, Kettlebell Instructor
Naina discovered kettlebells in 2005 and she has been hooked ever since. Unlike many fitness instructors, Naina’s comfort with physical fitness did not begin until her late twenties. She began her journey by following along with fitness videos in her living room and gradually built up the confidence to join a gym, where she learned how to use the weight machines and participated in some fitness classes. She soon graduated to using free weights. After swinging the kettlebell for about 30 seconds, she knew she had stumbled across something unique and powerful. Very quickly, the blend of resistance and cardio training provided by the kettlebell resulted in major gains in functional strength. No longer did she have to ask for help getting her luggage into an airplane overhead compartment! In addition, the confidence that that training provided empowered her to try new activities that she had only dreamed of like rock climbing, kayaking and snowboarding. By 2006, Naina had traded in her traditional gym workouts for kettlebell training and was inspired to work toward obtaining the RKC certification.
Naina earned her RKC Level 1 certification in Spring 2007 and was recently invited to assist at the national certification course. She works full-time in a non-fitness related environment and is uniquely qualified to teach as she has personally experienced the transformative power of kettlebells on the “50-hour plus work week body.”

David Helwig, RKC Instructor
David has been training with kettlebells since taking his first Jump Start class at Rapid Results Fitness in 2007. He was immediately fascinated by the pure simplicity of the kettlebell and the natural feeling of movement with the bell. He progressed quickly, developing a love for working towards perfect form and experiencing a newfound awareness of his body and its abilities. Interested in conquering the challenges of the RKC program, David went for, and received, his RKC Level 1 certification in April of 2010.
David has an undergraduate degree in psychology from the University of North Carolina, Chapel Hill. After graduating, he joined a computer software company in The Triangle. He continues working at this company as a technical support analyst.
Prior to discovering kettlebells, David enjoyed finessing cars around race tracks. Most of his driving has been at eastern tracks such as Sebring International Raceway, Road Atlanta, Virginia International Raceway, and Summit Point Motorsports Park. He finished first in his class in the North Carolina Autocross Championship in the early 90’s, then directed his focus to instructing teens and adults in car control and accident avoidance and in high speed performance driving.
David understands the importance of the quality of movement. Training with kettlebells, like racing, is more about developing the skill rather than the complexity, size, or horsepower of the equipment.
Jennie Brown, RKC I Instructor
Jennie has been a part of the Rapid Results Fitness family since July 2009. She completed the Russian Kettlebell Certification in April 2011 and happily joins the Rapid Results instructor team. Jennie received her BA from The University of Richmond. Her career was in the pharmaceutical industry but Jennie has taught various group fitness classes since college.
Jennie currently stays at home with her three children. “I have always been involved in some form of fitness. However, I have never participated in a fitness form as time efficient as Kettlebell training. This is the ideal workout for a busy mom that wants both strength and cardio conditioning; achieved in a time efficient manner. What makes the Kettlebell instruction at Rapid Results Fitness so unique is the focused attention you receive from the instructors. The environment is much more of a personal training situation which ensures proper form, safety and results in each workout.”
Jennie looks forward to assisting other clients in developing their full body awareness and potential with Kettlebell training; both in a personal training setting and the class setting.
Jennie is married and loves spending time with her family. She was born in Durham and has lived here since 2000. Jennie’s first fitness choice is Kettlebell training but she spends all the time she can outdoors.
