I love this gym because it takes me back to gyms in the 80's that u went in to get ur workout and left right after. No socializing for the most part just hitting iron and sweating to ur hearts content!

Grandslam is the absolute best gym in town, wouldn’t trade it for anything else. I’ve been going to Grandslam on and off as long I can remember. Way before I discovered bodybuilding. It’s came a long way from having batting cages and probably not even half the equipment it has to this day. To a full blown hard core looking gym for all builds and lifting sports, from bodybuilding, powerlifting, to Olympic lifting or just being all about health and fitness in General. I walk into the gym everyday and I get pumped just from the setting and how the gym looks. Makes me feel right at home especially since I bodybuilding with all the framed photos of old school to the current era of Elite Bodybuilders and gym posters that would just get you motivated. But overall hell yeah I’d recommend Grandslam to anyone and everyone who’s trying to get in shape or start lifting in general!

Of course I recommend this gym. It is by far the best gym in Delano and better than most gyms I’ve been to.

Had a great workout my first time in there was today they have a huge availability to heavy weights as well as equipment i usually go to athletix but for some reason they close from 1230 to 230 which was a hugr inconvenience for me considering the fact that i pay 35 dollara a month there and drive all thr way from Wasco to workout. Grand slam was badass 5 bucks for the day pass and i got a great workout in.
