Danielle Langolf
Danielle LangolfFitness & Conditioning Coach
Danielle Langolf, a native of Manhattan Beach, and has been in the fitness industry for 9 years. From the age 6 to 18 she played soccer and softball; after finishing with sports though she was at a loss on how to continue to stay active. That was until she decided to get her own personal trainer, which brought her to learn new ways to stay healthy and fit.
She adjusted her fitness and nutritional habits through making incremental changes to her daily routine to develop an achievable healthy lifestyle. Fast forward a decade later and working for fitness facilities like 24 Hour Fitness, South Bay Aquatics, and Bionic Body, she has continued pursuing her passions in fitness.

Danielle’s training style is: first establish a solid base with every client with regards to ankle, hip, and shoulder mobility while developing knee, core, and elbow stability. Once the client has appropriate range of motions and stabilities in all planes of motion, she then builds up their athletic abilities through functional sports performance based workouts. Her fitness style, while being beneficial for most sports, is particularly conducive for tennis performance due to the sport’s repetitive fast twitch nature which injuries frequent; her style works very well in helping with injury prevention and rehabilitation.

Today her programs incorporate similar philosophies that she practiced with her own trainer: she incrementally changes and challenges her clients’ workouts by progressing planned fitness programs at a rate achievable for each individual. While on the nutritional side she helps her clients develop healthier habits (not crash diets) by changing one agreed upon habit at a time; which over a short period of time adds up to a much healthier lifestyle! Her personal philosophy is the best years aren’t behind you, but ahead of you!
