Personal Trainer Opportunity at Growing Younger – Award-Winning Over 40s Gym & Physio in Howick

Do you love working with people over 40? Do you understand that bodies change, that recovery takes a bit longer, and that menopause, old injuries and busy lives all shape how someone trains?

If so, you'll fit right in at Growing Younger.

We're a professional, physio-supported studio in Howick, dedicated entirely to adults over 40. Our members aren't chasing six-packs. They want to stay strong, move well and keep doing the things they love for decades to come. We're looking for a coach who genuinely wants to help them get there.

And the best part? You won't spend your time chasing clients. We handle the marketing/sales and bring members to you, so you can focus on what you do best: coaching people and helping them get real results.

The Role

We're looking for a casual Personal Trainer for around 10-20 hours per week to start. You'll mostly deliver 1-on-1 personal training, and you'll also run small to medium-sized group sessions.

There will be a requirement to help with healthy nutrition habits, an understanding of calories, portion sizes and how that can affect body weight is desirable.

We need flexibility. You'll need to be available mornings and evenings on at least a couple of days per week, and Saturday mornings are preferred. We'll agree on your schedule with you.

Who We Are

Growing Younger is an award-winning fitness facility at 6/194 Moore Street, Howick, with a multi-disciplinary health and fitness team that includes physiotherapists, a chiropractor and an acupuncturist. We work exclusively with people over 40, helping our members lose weight, get stronger, boost their energy and manage chronic health conditions like high blood pressure. So far we've worked with close to 1,000 people over 40.

We're more than a gym. We're a community built on trust, accountability and real results. In 2020 we won the Innovation Award at the NZ Fitness Industry Awards for our unique approach to health and fitness.

You'll join a team of 5 personal trainers, 2 physiotherapists, a chiropractor and acupuncturist/massage therapist.

What We’re Looking For

You must:

Be REPs registered

Have a genuine interest in working with people over 40

Be available mornings and evenings on at least two days a week (Saturday mornings preferred)

Be punctual and reliable, because our clients count on their sessions starting on time

Be organised, able to manage your own caseload and follow simple systems and procedures

Communicate well and build strong rapport with clients

Be a team player, happy to work alongside our trainers and physio's

It's a bonus if you:

Have 3+ years of personal training experience

Have experience running group sessions

Have a basic understanding of healthy nutrition strategies

Don't tick every box? We'll consider all experience levels. If you're passionate about helping people over 40, we'd still love to hear from you.

What We Offer

$35 -$40 per hour (based on experience), plus 8% holiday pay

No rent, ever. You're paid to work here, not paying for the privilege.

Regular, consistent clients. Our members are on subscription-based training, so your diary stays steady week to week.

We bring the clients. We handle the marketing and sales, so you can focus on coaching.

Paid admin time, based on the number of clients in your care

Work alongside our in-house physio team. Ideal if you enjoy training around injuries and real-life bodies.

Free physio-led CPD that counts towards your REPs points

Monthly 1-on-1 caseload meetings with a senior trainer

Room to grow. As the studio expands, there's scope for more hours and responsibility for the right person.

A supportive, professional team that values trust, accountability and results
