About Me.

Hi! James de Lacey here. I own and run Sweet Science of Fighting. Strength & Conditioning is my passion to the point I made it my career so I could help athletes like you succeed in their sport. I hold a Master of Sport & Exercise Science and have published academic research. Further, I've worked in three countries at the elite and international level of sport preparing athletes for competition. I train and compete in BJJ and created Sweet Science of Fighting to bring you cutting edge training information from myself and high-level coaches you can access with a click of a button.
