Shape Shop Fitness & Nutrition has been Masterton's women-only strength training studio since 2015. Based in a well-equipped space on Lincoln Road — with the entrance on Railway Crescent — the studio offers supervised group strength training, small group personal training and nutrition coaching, all delivered in an environment that is deliberately supportive and judgement-free.
Training here is coach-led from start to finish. Group sizes are capped at 16 women, and each session follows a structured resistance-training circuit built around weight-based movements. Every lift is supervised and supported, so members get genuine coaching attention on technique rather than being left to work it out alone.
The timetable is built around three session styles: Strength sessions, traditional functional circuits of three sets of twelve reps across eight stations; Super sessions, faster full-body rounds through all eight stations; and Sweat sessions, timed circuits that blend weights with heart-raising movement. Beyond the group floor, one-on-one personal training is open to members and non-members alike, Focus Groups give experienced lifters coaching in groups of two to four, and Shape Shop Nutrition pairs fortnightly one-on-one coaching with a practical nutrition plan and a diverse selection of whole-food recipes.
Membership is deliberately flexible — unlimited supervised sessions with no joining fees, no cancellation fees and no contracts, and your rate stays grandfathered at the level you joined. New members get their first week free. The coaching team is led by co-owners Angela Smart and Regan Sherriff, alongside studio coaches Rachael Lewis, a competitive powerlifter, and Katie Macarthur.
Since 2015, Shape Shop has held a particular place in Masterton: a strength training studio exclusively for women, where every session is supervised and nobody trains alone. The premise is simple — a well-equipped studio, qualified coaches on the floor at all times, and a programme built around weight-based movement, so lifting feels approachable rather than intimidating. The team describes the environment as judgement-free, and the structure backs that up: group sizes are capped at 16 women so coaching attention never gets stretched thin.
The core offering is supervised group strength training. Each day follows a structured circuit designed to build full-body capability, confidence and long-term health, and every lift within it is supported by a coach. Membership is deliberately uncomplicated: unlimited access to supervised sessions, bookable as often as you like each week, with no joining fees, no cancellation fees and no contracts. Pricing is grandfathered, so you keep the rate you joined at, and your first week of membership is free — an easy way to see whether the studio fits before committing.
The timetable is built around three session formats, each with its own character. **Strength sessions** are traditional functional resistance-training circuits: three sets of twelve reps at each of eight stations, with the focus on solid technique and progressive overload. They run approximately 60 minutes and suit anyone who wants time under coaching to get movements right.
**Super sessions** compress the work: one set of twelve reps at each of the eight stations, repeated three times, for a fast-moving, weight-based workout of roughly 45 minutes that builds strength, stamina and efficiency.
**Sweat sessions** are the shortest at around 40 minutes — timed, functional circuits that blend weights-based cardio with movement patterns designed to lift your heart rate and keep you moving. They are a conditioning option for women who want to build fitness while still lifting.
Shape Shop also offers one-on-one personal training — sessions designed to sharpen technique, refresh movement patterns or give focused coaching on specific lifts. Notably, you don't need to be a member to book them; the sessions are open to everyone, whether you want expert eyes on your form, a confidence boost with key movements, or targeted guidance on a stubborn lift.
For more experienced strength clients, Focus Groups put two to four women in a session with a qualified coach, working on pushing limits, refining technique and developing targeted strength toward specific muscle-group goals.
Then there is Shape Shop Nutrition, a nutrition and habit-building program designed to help members move well, feel energised and build long-term consistency. It combines 70 minutes per fortnight of one-on-one coaching with a practical nutrition plan and a diverse recipe selection built around simple, whole-food eating — an approach shaped by co-owner Regan's love of recipe development.
The studio is co-owned by Angela Smart and Regan Sherriff. Ang leads client experience and coaches group fitness, nutrition and small-group personal training, with a strong focus on strength and form; she is also a dedicated runner who brings that performance mindset into her sessions. Reg specialises in functional strength, structured nutrition and small-group personal training. They are joined by studio coaches Rachael Lewis, a group fitness and nutrition coach who competes as a powerlifter and brings real-world heavy-lifting experience to her coaching, and Katie Macarthur, whose interest in body mechanics helps women move fast, strong and with confident technique.
Shape Shop sits at 132 Lincoln Road in Masterton — but note the entrance is on Railway Crescent.

Whether you have never touched a barbell or you are chasing a specific lift, the format is the same: a supervised circuit, a coach at your shoulder, and a room full of women training toward their own goals.
