California Fitness 24/7 is an easy-to-use and fully loaded gym with good amenities, including plenty of treadmills, steppers, and recumbent bikes. The layout is good, the facility is clean with clean restrooms, and the staff is outstanding and super nice. It is a quiet and chill place, described as an awesome little hole in the wall and the best little secret. The price is very reasonable, it is open 24/7, and its location is totally convenient and within walking distance of Main Street in Martinez. Parking can be tricky, and some equipment is older and needs new padding, but it remains a great place to get in and out quickly for a strong workout.
