What Parents are Saying

“Coach Marcus has been working with my son Sebastian for 4 years. Initially, my son was a single sport athlete (baseball) so the focus was mainly on improving speed and strength training along with injury prevention. Sebastian during his senior year decided to play football and run track. The work Sebastian had been performing with Coach Marcus paid off and transitioned well into these other sports. Coach Marcus is extremely knowledgeable but more importantly truly cares about the athletes he trains. He is great at connecting with athletes to understand their goals and to learn how to motivate the athlete to obtain those goals. I highly recommend Coach Marcus to anyone looking to improve their over all strength, agility, speed, explosiveness and build the supporting muscle structure for injury prevention."


"Marcus's youth training program is truly exceptional. My three children thoroughly enjoy their sessions with him. His expertise in speed training, weight training, and form correction has significantly benefited their athletic pursuits. The training has not only enhanced their performance but also boosted their confidence and motivation. I wholeheartedly endorse Ambition and Marcus to others seeking top-notch training for their kids."


"Leonardo admirably regained his speed and agility post-injury, culminating in dual championships during his senior year in both High School and Club rugby. Meanwhile, our 13-year-old, Sofia, remarkably elevated her speed by 3 MPH within four months, transitioning from a front row position to an impactful outside center in rugby. The pivotal role of speed manifested in the success of the Coronado High School Rugby Team, wherein MB's contributions prominently propelled the team to secure the 2023 High School Championship."
