About ProJackX

ProJackX was born out of Jack, the Founder who wanted to do something ethical. ProjackX gets its name from the strong belief he hold: that every client’s goal is a project to be delivered by a deadline. 

Their vision is to inspire people, help them discover who they really are, and make training with them the most incredible experience in a client's life journey. 

The founder of ProJackX, Jack, has dedicated the past five years of his life figuring out why it’s so hard for people to lose weight, and how come when they do manage to lose it, tend to put it back in a short period of time. He believes that this is one of the reasons why people become discouraged and become less inclined to engage personal trainers. 

Jack wanted to fix this, so he created ProJackX. Instead of strenuous workouts, heavy loads, and tough miserable diets, they help their clients build habits of training and eating healthy so that it becomes automatic and sustainable. The team at ProJackX doesn’t seek pride in making people tired. They find fulfilment in coaching people right.

They believe that weight loss is not rocket science, and that what’s required is merely the understanding that the body is a servant, so to work on the master.

ProJackX’s training program in three steps: 

  1. Habit formation 
  2. Behavior change 
  3. Continuous improvement

Jack Oberoi

Jack is obsessed with people. He feels an immense sense of fulfilment when he sees clients achieving fitness goals that they thought they never could. To him, this feeling is irreplaceable. 

He believes that a true Coach is one who makes his/her client fall in love with the things they once thought were really hard for them to do.

Some might perceive personal training as simply as vigorous workouts, expensive training, eating chicken breast and broccoli, and hitting goals within short periods. Jack doesn’t believe in any of these. Jack’s goal for his clients is to help them build a lifestyle, understand that training isn’t about intensity but consistency, and that training isn’t “one-size fits all”. 

He helps people understand their body type and safe training methods, builds a strong foundation for his clients by helping them master the right techniques, and prioritizes building long-term relationships with all his clients. 

During his free time, Jack enjoys reading books that will help him deliver more quality service and make him a better man.

What Customers Say

Testimonial of Bernard

"After running for many years and due to age, I started having knee and back aches. I couldn't keep up with the runs that I used to do, so I tried personal training with Jack to improve my overall fitness level and to build more muscle, stability and flexibility. After training with Jack, not only did my fitness improve, but the back and knee aches also went away.

Jack is knowledgeable in his field, but also people-oriented. He listens to his client's needs and makes sure that your training objectives are met. This is important since there is seldom a one-size fits all solution as each client has different needs."

"I met Jack coincidentally at Anson. He approached me with enthusiasm, seemed passionate about personal training and was genuinely interested in helping me further.

It's been a fruitful and fulfiling journey with Jack thus far. I've seen progression in my fitness and overall development individually and collectively. Jack's positive energy and passion towards training has been fantastic since day one and his love for training and genuine care for his clients shine through everyday.

Training with Jack at Core Collective has made me become more confident and I enjoy the process. The gym feels premium, like a private gym with premium quality service, it's always clean, well-equipped and I feel safe and at home."
