Chris started his sports career playing recreational soccer. He played table tennis for almost seven years. During that time he started his martial arts career in 2003 doing Goju-Ryu Karate and finally earning his black belt in 2012.

In 2014 he first stepped into a CrossFit box and knew that this training method fits perfectly for him. As time flew by he has visited over 40 CrossFit boxes all over the world and he’s happy to get in touch with this great community in all the different places.

Kai started CrossFit in April 2016 to lose weight and get fitter for improving his overall health. Since than he has lost over 46kg (101lbs) and his overweight related health issues disapeared. In June 2016 he joined Crossfit Assault. Coach Olliver challenged him a lot in terms of improving his workout performances and following a nutrition plan to achieve his desired body composition and shadowing to become a better coach.
What this all taught his is, that “CrossFit is not just about getting fitter and healthier but it also helps to translate experiences from challenges in the sport to challenges in life. There is no right or wrong, just do it. That’s my goal for my clients.”

What is Strength and Conditioning?

Strength and Conditioning (S&C) is more than just lifting weights.

S&C involves any activity used to enhance and facilitate performance. These activities include, but are not limited to running, jumping, agility, core and endurance training.

Your S&C coach has two primary goals. The first is to improve athletic performance, which usually means improving athletes’ speed, strength,and power (although specifics vary according to athlete and sport).

This usually includes teaching proper lifting techniques, supervising and motivating athletes as they work out, and assessing their performance before and after the program.

The second primary goal is to reduce athletic injuries, to strengthen body parts that are prone to injury in a particular sport.

Join our Strength and Conditioning Class with CrossFit Level 2 Coach Olliver every Tuesday @18:15 and Saturday @0900.

Mike | Headcoach, Owner


As the owner of CrossFit Assault Stuttgart, Mike is passionate about the sport and introducing it to new people. He has 25 years of fitness training with 15 years of martial arts and 10 years of American Football. After reading about „The Definition of Fitness“ on the CrossFit mainpage, Mike knew he was hooked on CrossFit and began his certifications and opened his own CrossFit Gym.

Mike feels that the functional fitness of CrossFit prepares athletes for any situation in „real life“ and that most work outs deliver crossover benefits to other movements that you wouldn’t have expected. He likes to see the athletes constantly improving in CrossFit.

CrossFit has highly qualified Coaches who are there to support in the constant improvement of the sport. Every work out is a challenge and it’s great that in CrossFit, each athlete has support from each other. The atmosphere in a CrossFit Gym is in no way comparable to a regular gym. In CrossFit, everyone works out together and encourages each other to improve each time. These athletes are willing to make great efforts in order to improve their health and achieve the results they are looking for.

“Do not wait to start CF just because you are worried that you are not fit enough for the workouts. Any workout will be scaled to the intensity level that you can handle. Don’t waste your time “getting in shape” before starting – CrossFit gets you fit! Forget about trying to look good during a CF workout… if that happens, you’re not working hard enough!”
