Kisha Wilson


Kisha’s fitness journey began in high school by taking weight training class as an elective. She fell in love with the weights and never stopped working out! After high school, she competed in several national level figure competitions. She then found CrossFit and discovered a brand new way to train which led her to give up bodybuilding and dive in head first. She began coaching in 2011, and followed Invictus Athlete remotely for nearly 9 years before joining the Invictus coaching staff. Prior to joining Invictus, she owned and managed two affiliates of my own. She is USA Weightlifting & CrossFit Level 2 certified. She loves the community of CrossFit and helping individuals reach their health and fitness goals. In her downtime, she enjoys spending time with her three kitties, going to the beach and riding her motorcycle!

During your first 1-on-1 session, the coach will get to know you, your goals and any previous history you have with fitness and general health. These sessions are highly individualized and can span topics from nutrition to previous injuries. Then we’ll help determine and create a workout plan that is personalized for you. No matter what fitness experience you have, our coaches will meet you where you’re at and make you feel at home! Most importantly, you’ll be introduced to the Invictus culture—a family of like-minded people who are passionate, knowledgeable and want you to reach your fitness goals.


Drop-In Policy:

Out-of-town visitors are welcome to drop into any of our normally scheduled group coaching sessions for $30 per visit or $85 for a week. The joy of CrossFit has always been in the community of amazing individuals, and we never want to lose sight of that.

Open Gym Policy:

Invictus is an all-coaching facility. We have a staff of expert coaches and want all of our members and visitors to benefit from them. However, we do offer open gym from 7:00 a.m. to 4:00 p.m. Monday through Friday, and from 8:00 a.m. to 11:00 a.m. on Saturdays. We will always do our best to accommodate open gym guests, but our regularly scheduled group and private sessions will have priority over space and equipment.

Semi-Private Coaching:

Invictus coaches are available for semi-private coaching sessions throughout the day. To inquire about our schedule private coaching with an Invictus coach, please give us a call at (619) 231-3000.

What should I expect in my first 1-on-1 session?

This is our chance to get to know you, your goals and any previous history you have with fitness and general health. These sessions are highly individualized and can span topics from nutrition to previous injuries. These sessions may, but will not necessarily, include a physical movement assessment and light workout. Before you leave, you will have a clear understanding of how our gym works, and the best next steps for you to achieve your goals.

Is there a kids area? Is it supervised?

Yes, there is a kids’ area where you can see your little ones and they can see you while you workout. The area is not supervised and Invictus is not responsible for activities carried out in the kids’ area.

Is Invictus only for competitors?

Invictus has enjoyed competitive success in the sport of CrossFit, but our competitive athletes make up less than 1% of the people we serve. The vast majority of our members are looking to improve their health and vitality, not compete. Our success stories include, among others, working professionals who have lost 40 lbs in just 8 weeks of training with us, women who have rediscovered their power and athleticism, recreational runners who have shattered personal best 5k and marathon times, and professional athletes who have gone on to win their sport’s ultimate prize.

Am I fit enough for Invictus?

You don’t have to be of any certain ‘fitness level’ to start a workout program, especially not at Invictus. When you look around the gym at any given time, you will see all types of people who are enjoying the camaraderie of participating in the same workout as each other while doing completely different versions based on their level of fitness or comfort with the movement. One of the best things about having a coach is that there is someone there to make sure you are pushing yourself to the level of your ability and sometimes this means helping you make the workout more ‘manageable’. We’ve all been there so everyone is non-judgmental and super supportive!

What makes Invictus different than other CrossFit gyms?

Our professional coaching staff and community are the most compelling reasons to be part of Invictus, but we also offer some more tangible benefits that you’re unlikely to find elsewhere.

We offer more than 11 group coaching sessions per day, 7 different goal-based programs (everything from guided nutrition programs to Olympic weightlifting and CrossFit). We have dedicated kids’ areas, showers and towel service – among a host of other membership benefits.

Best of all, as a member, you’ll have a dedicated coach that is not only there to educate you and fix form, but they also serve as your guide and support person.  They will help you customize your workouts and experience so you can be sure to reach whatever goal or goals keep you coming in.

Have Limitations: 

We know some of the biggest worries people have about starting CrossFit are whether or not they can ‘survive’ all the workouts. This is a legitimate concern with any new workout regimen and we are proud that our world-class coaches expertly customize the workouts for and watch each member to ensure workouts are challenging, yet doable, and safe for each individual.

Whether you’re coming in with an acute injury or have a rap sheet of chronic problems and pains, we’ve got you covered. Our coaches are experts at customizing workouts and prescribing exercises to not only work around your limitations, but also help you to improve them with corrective exercises and mobility work.

Because of their great care and knowledge in these areas and focus on proper technique before adding weight or speed to movements, you don’t have to worry about getting injured in the gym. In fact, the things you will learn about properly moving your body and weights will both strengthen you and give you knowledge to prevent injuries.
