“This is NOT your generic box. Coaches are well-trained and provide exceptional, cutting edge training and advice. They are knowledgable about integrative approaches to health (eating, sleep, hormones, psychological wellbeing). I was most impressed when I was in the process of attempting to get pregnant. Hands down the Best!“

Manny Diaz
“I moved away from San Juan a decade ago before Crossfit was introduced to the island and I was not sure what it would be like dropping into a box here. Aggressive is excellent, well staffed, well equipped, and well located in an easy-to-find space in the Santurce area. I dropped in at 10 am on Saturday and was treated with excellent hospitality. Ernesto was a great coach. Welcoming to athletes of all levels and disciplines (CrossFit, powerlifting, Olympic lifting, gymnastics). I will drop in next time I visit my hometown.“
