What Our Clients Say
EXCELLENT Based on 78 reviews Michael Robinson2025-09-08Trustindex verifies that the original source of the review is Google. The reason I chose Fit4Blast over other personal training gyms in Piscataway is the flexibility. I can book sessions around my schedule, and whether it’s with Jayson, Peter, or Koelle, the workouts always match my program. Olivier sets the standard by showing how much he values every client’s progress. After three months, I’m stronger, leaner, and more confident than ever. Brandon Foster2025-09-08Trustindex verifies that the original source of the review is Google. The trainers here are top notch. They push me to my limits in a safe way and keep me consistent. I have gained muscle and lost fat while improving my mobility which has made a huge difference in my daily life. lordstylebnc2025-09-02Trustindex verifies that the original source of the review is Google. My best personal training expérience. Very knowlegable and highly recommended! Jason Thompson2025-08-28Trustindex verifies that the original source of the review is Google. Before Fit4Blast, I struggled to put on size. Now, after four months of consistent sessions, I’ve gained 12 pounds of lean muscle. Olivier Lucenay often checks in and shows how much he cares about client progress, which is rare to find in a gym. Koelle has been amazing at pushing me just enough without risking injury. Fit4Blast Personal Training Piscataway really feels like family. Priya Sharma2025-08-27Trustindex verifies that the original source of the review is Google. I joined Fit4Blast Personal Training in Piscataway six months ago, and I’ve already lost 22 pounds. The best part is how flexible the schedule is. I can train with Edmond on Mondays and still have Jayson continue my program later in the week without missing a beat. The trainers all work as a team, which makes progress feel seamless. The private gym is spotless, and I always feel motivated walking in. Ral W.Meritt2025-02-07Trustindex verifies that the original source of the review is Google. Tony has been exceptional!

She tailored each session to my fitness level, the nutritionist-designed meal plan was a perfect complement and to the workouts. I’ve seen results much faster than I expected! Amit Gupta2025-01-30Trustindex verifies that the original source of the review is Google. I’ve trained with Jeff at the private Fit4Blast facility, and it’s been a game-changer. The focused, distraction-free environment is perfect for anyone serious about their fitness goals. Jeff’s workouts are always challenging yet fun, and the meal plan created by their nutritionist has helped me improve my diet significantly. Ashley Rosa2025-01-29Trustindex verifies that the original source of the review is Google. Neha trained me at my apartment gym in Jersey City, and she’s amazing!
