Your next 3 steps with FONSECA

1-1 Discovery Call with Megan!

You’ll start your journey with a discovery call with Megan to discuss where you’re currently at with your health & fitness.

We know a lot of women haven’t been in a gym before or for a very long time, so it’s a wonderful time for us to get to know you!

Megan will get you booked in for your first in person 1-1 with Arabella to discuss your current movement and aesthetic goals.

From there we will set you some initial goals for both lifestyle and nutrition (if wanted) to get the most out of your training journey.

Initial Assessment in the Gym

You’ll then have your very first 50 minute assessment session with one of the team. This is so we can assess your current strength, fitness and mobility.

From there we will write up a programme for you to join our Small Group Personal Training Sessions.

  • An elderly woman in black workout clothes is lifting a barbell with red and gray weight plates at the gym.

    "I'm really enjoying the relaxed environment. I love the friendships I've made and I love the support from everyone. I'm regaining my confidence every day" - Sandra Brewer

  • A smiling woman with curly blonde hair in a pink athletic tank top standing in a gym with workout equipment and weights.

    "Immediately I was made to feel welcomed, supported and not out of place. I love going to my PT sessions, the coaches and ladies that attend are all encouraging. I feel fitter, stronger and happy" - Kim Turvey

  • A smiling woman with shoulder-length gray hair wearing a lime green quarter-zip sweater, standing inside a gym with workout equipment in the background.

    "I was so so nervous when I first came, but the team have all been amazing. I wasn't looking for a women's only gym but now I love it. Everyone is so friendly and my doubts have disappeared" - Karen Randall

  • A woman smiling with her hands on her hips in a gym, wearing a black T-shirt and leopard print shorts.

    "Before I started I thought I hated all exercise, turns out I just didn't like the environments or the fact I didn't know what I was doing. It's an addiction I don't ever want to give up" - Sammy Saunders

  • Woman smiling at the camera in a gym or fitness studio with people exercising on mats in the background.

    "I decided to join SGPT this year and it's been the best decision I've ever made. The plans and community have helped me build confidence, develop healthier habits and kept me accountable. It's also reframed how I look at exercise and it's so much more than fat loss." - Rach Clark

  • A woman in black workout attire standing in a gym with dumbbells in the background.

    "I've come down two dress sizes and my strength is phenomenal. I joined Fonseca Fitness in April 2024. I was severly overweight and it was difficult for me, but so glad I did! The community is so supportive and I have made some fabulous friends too. I am still on my journey but I will get there soon!" - Mandy Hunt

  • A smiling woman standing in a gym, wearing a gray Adidas T-shirt with blue logo.

    "10 months in, I'm 5 stone and 4 dress sizes down and I have muscles! As a plus size woman, in her mid 30's I really wanted a women's only gym, free of judgement, where I could feel safe and supported. What I found was so much more than that. I found a group of women who are exceptional - women who cheer each other one, laugh with you and support you" - Claire Sullivan

  • A smiling woman in workout clothes standing outside of a fitness center. The fitness center sign reads 'ONSECA FITNESS: THE HEART OF FEMALE WELLNESS,' and she is positioned near the entrance.

    I've dropped 2 dress sizes since joining. Fonseca Fitness really is a gym family where ordinary women achieve extraordinary things together. I joined FF in March 2025 and my personalised programme has grown with strength, skills and confidence. For an uncoordinated beginner, no question has ever been silly and the ladies make me feel encouraged and motivated" - Julie Cottam

What does your initial 6 weeks look like with us?

  • We believe in keeping things simple, yet intimate. We know the names, ages, careers, etc of every woman who walks through our door. We are not a commercial gym and we pride ourselves on that.

    We ask that every woman in our community starts with committing 3 hours a week to themselves, with 3 small group personal training sessions per week with us.

    You’ll start with an initial 1-1 with Arabella, who will take all your measurements, discuss and set goals for your nutrition as well as set your lifestyle goals.

    From there, we will write you up your personalised programme, which we will go through with you every time yo walk through the door. You are never left in the gym on your own, to just wing it.

  • 6 weeks is the key amount of time in order to make a new habit part of your lifestyle.

    Within that time frame we see women change in confidence levels both in and out of the gym, strength improve and body fat drop.

    It is the perfect amount of time to prove to yourself, you can do this!
