About Grisselle

My favorite client story

A client had a back injury and was nervous to deadlift. The first couple of months was to practice safety first and the basic movements without weight. After 3 months, he was able to 20kg of weight without hesitation or pain, and felt more confident in his movements. From someone to be nervous about lifting 10kg with a kettlebell because they thought they were going to get a back injury, but actually ended up moving better and getting stronger will always be a favourite client story, and means that I did my job as a coach.

My favorite exercise

Conventional barbell deadlift.

My training philosophy

I create customized programs to each individual, with the intent get stronger, move better, and feel empowered through strength training.

My training experience

I've worked in big box gyms like New York Sports Club, Crunch, along with boutique gym(s) like Body Space Fitness and TS Fitness; and independent training with private clients. Those experiences have included working with general population and athletes usually in grappling such as Brazilian Jiu-Jitsu or wrestling.

Fantastic trainer. She’s knowledgeable, patient and enthusiastic. She helped me ease into training. Largely focused on proper form to ensure I reach my goals, while avoiding injury

I was really sceptical about getting a trainer. I'd usually just go to a small gym by me, and wasn't getting the results I wanted. A friend referred me to Grisselle, and she's been training with for a while. I love how patient, knowledgable and empathetic she is. Definitely recommend!

Grisselle is a great trainer, educated and accommodating. She's also pretty easy going and didn't get frustrated either. I don't come from an athletic or fitness background, and it was a bit nerve-wracking for me at first. It was really reassuring that she simplified exercises for me and that she knows her stuff.

I’ve been searching for a personal trainer but was finding the process a bit intimidating. A friend referred me to Grisselle and I’ve been training with her twice a week for a few months already. She’s amazing. She makes me feel comfortable and it’s not pushy. She asked me what are my goals, set up a plan and it’s been great. She gives me lots of advice. It’s been life changing for the best. Can’t thank her enough.
