Weight training and running on and off for years. But. Mostly on my own and I could never stick with it. About 8 months ago I started going to crossfit and it's been life changing. I go between 5-10 hrs/wk. I'm in the best shape of my life, my lifts are heavier than I ever imagined (501 lb deadlift) and I love it. The class and social structure is perfect and United Barbell is right at the 4th st Caltrain location so it's super convenient.
