About Hetty

Hi there, my name is Hetty Diep and I have a holistic approach to fitness and wellness. I program by six week cycles according to your lifestyle goals. Your program includes 1) a custom nutrition plan and 2) a personalized training regimen. I program according to your knowledge and experience and meet you at the pace you're ready to begin with. My approach is steady and based on long-term results. 

I work with couples and individuals privately in Los Angeles. I am experienced in working with ages from 19 to 65 and typically get along with open-minded individuals who have a very strong-willed mindset in reaching their lifestyle goals. My clients are committed to longevity and overall wellness.

Our time, energy, and progress is important, therefore, all programs are customized in advanced and personalized according to the time you wake, work, sleep and play. Those who are willing to be pushed and encouraged to continually reach new heights will thrive with me as I will make sure you get where you aim to go. I love helping those who want to be helped. Life is short - there's no time for BS!

Hetty is by far the best personal trainer I've ever had. She listened to what I was trying to accomplish and created a great plan for me. I've had great results and I'm in the best shape of me life! She takes her job seriously and is also a fun person to work with! She's incredibly attentive and upbeat -- making it fun to workout!

Been training under Hetty for a year and the results have been nothing short of amazing. At 38 I went from the worst shape of my life to the best. She will create the best program tailored to your specific goals. Her tireless commitment to the client is something you don't often see anymore. All I can say is TRUST THE PROCESS! I would also suggest investing in her meal prep program. You will get all the nutrients you need which will accelerate your path to real fitness. Lastly, her programs will lessen/eliminate long time aches & pains in your body. It is very nice living with no back or knee pain for the first time in a decade. Highly recommended!

I've never seen anyone more passionate than Hetty in creating THE PROGRAM that absolutely best fits your needs and your workout level. Even if you've never touched a barbell before in your life, Hetty will accommodate with basic movements that will maximize results. It's unbelievable. It's not just some generic program that is a cookie cutter. Hetty will write out your programs for you and it differs month to month so that your body won't adapt to the program and become stagnant. You will see results if you keep up with her program. HIGHLY RECOMMENDED!
