3D Fitness Personal Trainer

Here’s what makes us different: classes are capped at 12 people, so nobody gets lost in the crowd. We’re the owners and we’re on the floor coaching — we know every member by name, we watch every rep, and we scale every exercise to your level. Whether you haven’t trained in years or you’ve been at it your whole life, you’ll fit right in. Every 45-minute class blends strength training and cardio — so you’re building muscle and conditioning your heart and lungs in the same session. The workouts change daily, so you’ll never get bored and never plateau. Most of our members are busy professionals and parents in their 30s, 40s and 50s who want to get stronger, move better, and feel looked after without the intimidation of a big gym. Come see why 300+ people have given us five stars. Your first class is easy to book — and if you’re nervous walking in, don’t be. Making first-timers feel at home is kind of our thing.

I've been going to 3D Fitness 4-5x/week for the past three years -- including all the way through my first pregnancy -- and it's easily one of the best decisions I've made. The workouts are...

Love coming here! Been coming since September 2025, and it's exceeded all expectations for this 50+ year old who's never been able to commit to a gym (and wasted so much in membership fees!) in...
