I'm traveling in Oahu and California for about 3 weeks next month and I don't want to lose all my gains while I'm there. I want to take a day or two and visit some dedicated powerlifting gyms, since I never been one. The only ones I know are the ones I've seen on youtube like Untamed Strength or Barbell Brigade. A quick google search showed me TNG in Oahu which is a dedicated Oly lifting gym. I wonder if they can teach me some basics in a day. Any recommendations for gyms in Oahu/Bay Area/LA that have day passes?
