Ive been training with Oscar at iBSmartFitness for about a month, and Im already noticing real improvements. His sessions are both challenging and safe. Hes very attentive to posture and form, which makes a big difference. Each workout builds on the last without ever feeling repetitive or boring, and his communication style is clear and motivating. I always leave feeling stronger and more confident. I highly recommend training with Oscar if youre looking for effective, thoughtful, and engaging personal training!

Iosif is an excellent trainer! I used to train extensively when I was younger, but I had to stop for a decade due to an injury. Iosif was able to create a challenging yet manageable training program that keeps me motivated and prevents me from giving up. During our workouts, he’s always fun to talk to and provides valuable insights on how to improve both physically and mentally. I highly recommend reaching out to him to see how he can help you get started on your fitness journey as well!

He is an excellent guide and teacher, always able to cut through the overwhelming amount of conflicting fitness information and focus on what truly works for me. Iosif’s expertise, combined with his straightforward and supportive approach, has made a real difference in my journey toward feeling fit and confident. I highly recommend his expertise and commitment to my strength training goals.

Iosef is a pleasure to work with. He keeps you engaged and motivated to push yourself but also ensures you focus on form and not injure yourself. In my case, he was also dealing with medical constraints and went above and beyond to study what would benefit me and adapt the workouts to my needs.
