Testimonials

Hello my name is Mauricio and before I started training with Sebastian I was 130 pounds, skinny  and had improper functionality on the basketball court. Now after just 8 weeks of high intensity strength and performance training I have went up to 145 pounds while still staying lean with Sebastian’s athlete weight gain diet. On the basketball court, I feel faster and more comfortable on all of my moves as well. Sebastian always kept me motivated and taught me what it takes to be a high level athlete. I 100% recommend Sebastian and G89 fitness to improve and get to your goals!

Hi my name is Gavin Mortazavi and I’m a senior football player at Miami palmetto high school. When I got in contact with Sebastian I started at around 200 pounds being muscular as well as having too much fat on my frame. The goal was to cut down my fat while adding on muscle mass with a high protein low carb and zero sugar diet, mainly eating proteins such as chicken and ground beef. Losing 16 pounds of fat in 3 months I have gotten down to 184 lbs. and my body composition has changed drastically!

Hello my name is John Metellus and back when I was very skinny I had a low self-esteem and didn't know what to do. I didn't give too much thought about lifting weights until one day I met Sebastian Guitian through some mutual friends and the rest was history! He taught me a proper diet and emphasized the importance of a consistent weight lifting program and now I can say I've come a long way since then. I’ve gained 15 pounds of solid muscle while still keeping shape for my season! The process realistically took me 16 months with ups and downs, but overall we kept the remote training and diet consistent for great results.

“My name is Carlos Luis I started with G89 Fitness in October 2022 at 278 lb my height is 5’9 and I’m 21 years old. Currently I am 9 months into my journey weighing in at 225 lb, with consistent workouts and a specialized diet I have been able to drop body fat drastically while increasing muscle mass.

Hello my name is Ege Ergen and I’m from Istanbul, Turkey. I have been working out for two years but I first got in contact with Sebastian three months ago because I wanted to gain quality weight and get better results in the gym. 

I felt I plateaued while trying to get results on my own, but with Sebastian’s weight gain and workout program he gave me through his remote coaching I look bigger and I gained strength as well. He’s very patient with his clients and always understands how to make the best of what you have while still holding you accountable! 

“Hi my name is Pablo Velazquez I first contacted Sebastian when I started to see my weight increase just by looking in the mirror my face and body were at their biggest point. I weighed over 180 pounds at the time and I’m 5’8. I didn’t like how I looked so I decided to get a trainer cause I didn’t really know how to get the best results fast. The first couple of weeks were hard because of the no carb/low carb diet but with Sebastian’s help and tricks he taught me cheats and ways of eating good while getting my daily protein in. 

The workouts and training sessions are always a great vibe. Sebastian is very good at pushing his clients and knowing there limits and how to break them. Not only is he very well taught, he’s very patient with you as well. He helped me perfect my form and execute work outs perfectly and safely. Giving me a full diet plan and workout while going to him three times a week I have been able to transform my body in a matter of months.”
