LUCA RUSSO

Professional Soccer Player · Italy

“At 18 I play for a professional soccer team in Italy fighting for a starting spot. Every day Jacques pushed my boundaries. I went from a 235 pound hex bar deadlift for 5 reps to a 405 pound hex bar deadlift for 3 reps. My dumbbell rows improved from 45 pounds to almost 100 pounds for 5 reps. I also improved my 40 yard sprint time from around 4.65 seconds to a low 4.5. Beyond the gym I developed a stronger mindset. I am incredibly grateful to Jacques. His sometimes brutal honesty has given me the confidence to achieve my goals.”

What They Say

INDIVIDUALS THAT WE TRAIN LIKE ATHLETES

“After three years the improvement in my golf game has been substantial. Driving distance improved from 240 to 265 yards. Iron distances ball striking consistency and short game accuracy have all come around significantly.”

Toyo S.

Golf Performance

“Since I started working with Sirens and Titans I am able to play pain free often multiple days in a row. This is the only gym where my wife never wants to miss a workout.”

Larry J.

Golf · Pain Elimination

“The Sirens and Titans program has enabled me to recover power and endurance I thought I had lost ten years ago. I am making these gains with two intense thirty minute workouts a week. I honestly feel like I have rolled the clock back.”

Randy P.

Competitive Cyclist

“The beauty of S&TF is that my kick ass core building muscle toning heart pumping workout is done in just half an hour and I achieve better results than running stairs or doing yoga for an hour.”
