Meet The Team

We’re Henkie and Pauline Groenewald, passionate personal trainers who believe that everyone deserves to feel stronger, healthier and more confident regardless of age or fitness level.

HENKIE GROENEWALD

HENKIE GROENEWALD

Co-owner | Head Trainer | Personal Trainer | Sports & Performance Specialist
Henkie is the Head Trainer at Gymtivity and the driving force behind our day-to-day personal training and small group sessions.

A passionate sportsman and experienced Personal Trainer, Henkie has an impressive sporting background. He represented The Sharks Rugby 7s team, where he was appointed Captain in 2016, and currently plays for Hillcrest Villagers. He also represented South Africa Schools in both Athletics and Rugby.

Henkie holds a Diploma in Sports Management and an Exercise Science Certificate, and was awarded Best Group Exercise Instructor in KwaZulu-Natal in 2017. Henkie also qualified as a Facia Release and Muscle Activation Practitioner through Be Activated.

His extensive sporting experience has given him a particular passion for sports-specific training, strength and conditioning and performance training. He also has a natural ability to connect with younger clients and is particularly good at making exercise enjoyable and engaging for kids.

At Gymtivity, Henkie works with clients of all ages and fitness levels — from people starting their fitness journey to experienced athletes wanting to improve their strength, fitness or sporting performance.

Outside the gym, Henkie enjoys mountain biking, camping, trail running, rugby and bass fishing — often alongside Pauline.

Henkie's philosophy: Train with purpose, work hard and enjoy the process.
PAULINE GROENEWALD

PAULINE GROENEWALD

Co-owner | Certified Personal Trainer | Fitness & Wellness
Pauline is a qualified Personal Trainer and Fitness Instructor, a mother of two and a former fitness model who was sponsored by Biogen and featured in Fitness Magazine and Dis-Chem promotional material.

She completed her Personal Training qualification through ETA with a distinction and has many years of experience in fitness, training and wellness.

While Pauline has another full-time professional role, she remains actively involved with Gymtivity and assists with busy group sessions, special requests and one-on-one training by arrangement.

Now approaching 51, Pauline brings a particularly relatable perspective for women who are navigating the changes that come with getting older. She understands that your body, metabolism, recovery and priorities can change significantly through your 40s and 50s, and is passionate about helping women stay strong, active and confident through perimenopause, menopause and beyond.

Her approach is realistic and balanced — focusing on strength, movement, sustainable nutrition and lifestyle habits rather than quick fixes or extreme approaches.

Pauline is also the owner of Body Flow Studio, and her interest in fascia, body rolling and recovery complements the training philosophy at Gymtivity.

When she's not working, Pauline loves gardening, the outdoors, hiking, mountain biking, bass fishing and spending time in nature with her two Bosties.

Pauline's philosophy: It's never too late to get stronger, feel better and invest in your health.
