No matter how big or small the fitness goal, I can design a custom San Diego personal training program or nutrition plan for you. With my workout technique, Nikol Klein Method, you will never get the same workout twice and you can be confident that you won’t build up bulky muscles.

Best of all, you don’t have to even enter a crowded and uncomfortable gym!

“I lost 30 pounds before my Wedding!”

Nikol also uses the most effective workout equipment including The Human Trainer suspension training, offering more versatility than TRX or traditional equipment found in your local gym.

“I am ecstatic with the results I've seen in only the short period of time that Nikol has been my San Diego personal trainer! I have seen a change not only in my physical appearance and endurance but in my energy level and overall attitude towards working out. I used to dread going to the gym or even a simple jog but now I look forward to the days we train together! Nikol excels at working on exactly what your particular body needs are and helping to strengthen weak areas. I absolutely love Nikol as a trainer, and LOVE the results!”

Not only has she helped me lose weight and tone my body but has also been a huge influence in self-confidence and self esteem. I would recommend Nikol to anyone. Her knowledge of the body, muscles and dance background make her one of the most talented and respected trainers I have ever met. I encourage anyone to look into her services; she has been a blessing to me!”

-Sarah Zimmer, San Diego, California

As a Women’s fitness expert and professional ballet dancer, I know all of the secret training techniques to get you a lean, bulk-free body. You won’t find these exercises anywhere else or at your local gym because they have been created by me!  These exercises have been designed by me specifically for you, the Woman who wants a slim and toned yet not overly-muscular body.

"Nikol has completely transformed my body. I knew she was the perfect trainer for me from the second we met. Nikol took the time to listen to me about how I felt and what my goals were. She pushed me in my workouts and continually built me up with her unconditional support. She genuinely cares about her clients and wants them to look and feel good. She continues to push me and has inspired me to take pride in my body and my health. I have gained an incredible sense of self confidence and can honestly say that I LOVE my body. Training with Nikol is the best decision I have ever made!"

“I gained a lot of weight during my pregnancy. Balancing taking care of my baby and working out was quite a challenge. Four months after I had my son, I finally got frustrated with the lack of results and that’s when I found Nikol. Since I've been working with Nikol at her Del Mar studio, doing 30 minute personal training sessions 3 times per week, I've lost 16 inches so far and at least 15 pounds within the last 2 and a half months! I could see and feel results within the first week.  I would recommend Nikol to everyone and her 30 minute sessions are very convenient for me as a busy mom as the results are absolutely amazing!”

-Christina Sikes, San Diego, California

“I’m now below my pre-pregnancy weight!”
