    Been personal-training with Donnovan for a couple months now. I came in as a very skinny guy looking to regain + build new strength after years of circumstantial neglect, and he’s been great at adjusting pacing, introducing movements to learn to recruit dormant muscles, and keeping me progressing consistently on raw strength. He’s also fun to work out with, we usually yap about everything from music to AI agents to mental health and lifestyle.

    The gym itself is also a nice environment - feels positive and wellness oriented. The perks (unlimited dexa scans, recovery room, etc) are nice too!
