I’m so glad that jay help me out with my shoulder pain it was just a Miracle , within two weeks I get back to normal, I recommend jay to everyone I know



I have been training consistently for about 2 years now and of course like everyone else we all hit plateaus and don’t see the results that we desire, then one day I met Jay at my local gym he gave me honest feedback as well as a solution to my problem, that’s where he taught me about supplements I should be taking as well as how to properly diet. As soon as I took his advice I started seeing changes, with his honest feedback he always pushes me to challenge myself, when it comes to training and nutrition he really knows what he is talking about!

I’ve been training with Jay for almost 1 month now, and believe he is one of the most experienced & committed trainers I have ever had. I started training twice a week, really enjoyed the variety & challenge he put into the sessions & even the nutritional guidance as well!

I must be a glutton for punishment.

Jay is focused on helping me achieve my goals and makes every session challenging (& somehow weirdly fun). My fitness has increased noticeably and I’ve seen improvements in my body sculptor from core exercises, lift progressively heavier weights & generally push myself harder throughout each session. I find I actually look forward to my workouts.


– He ensures that my technique is always correct to avoid any injuries.

– He is extremely reliable & punctual – always set up & ready to start training ahead of time, with an exercise routine planned.

Jay's determination has instilled a level of determination within my own self and recommend him.

I met Jay at our local gym. I had just started working out again after 2 years due to pregnancy and being a stay home mom. I thought it would be a breeze and my goals would happen within a few months.
I ended up being depressed because my post pregnancy body was nothing like my old figure.
Jay has been so helpful to me not only with my workout routine but building my confidence and reminding me that everything takes time. He also gives me great advice on what I can do if can't make the gym and how I can achieve a better body by changing my eating habits. Since day 1 he has been such a great mentor, trainer, and friend to me.
I appreciate all that you do!

Jay has helped me out on a couple different fronts. A few months ago i plateaued. He gave me a couple tips on supplements i could try. The supplements helped me break thru. I hit a wall again and after discussing my nutrition and making a couple of tweaks i've loss additional weight. He knows what he's talking about.



Jay has been as a great personal trainer and nutrition coach for me. He helped me to get back in shape after I gave birth to my baby girl. His exercise routines worked well for by body to adjust quickly and efficiently. Jay is very knowledgeable, he explains well which exercises target which muscles, he personalizes my nutrition diet plan in a way that I don’t have to give up my favorite food and always comes up with some creative ideas. Highly recommend!

I still could eat my favorite treats!

Jay has helped me with my stress, energy levels, improve my eatings habits and make healthier choices. With his nutrition coaching approach and right supplementation recommendations, I now have been able to successfully lose weight and keep it off in and outside the gym, especially off the seat!
