Katja is the fitness sensation on TikTok. The licensed personal trainer provides her rapidly growing community with home workouts and nutrition tips. In doing so, she reinforces the positive trend of wanting to be healthy and fit – instead of hungry and slim. Katja not only has an enviable six- pack, however, but also acting talent. She lightens up her feed with entertaining videos in which she recreates typical situations from the gym and imitates workout types with Lipsync. Katja doesn’t take herself too seriously either. This makes her even more likeable, so that you don’t just want to book a training session with her, but also look forward to chatting afterwards.
