Killer X Training with Brittany
that class is a hot mess. theres not much instruction other than for 5 minutes at the beginning of each round. i sweated and will probably be sore tomorrow but overall didnt enjoy the class or feel motivated.
Killer X Training with Ben
Instructor warns you that this is a very fast paced boot camp style class. Not for those just getting back into working out. As a first timer, it was difficult to remember all the combinations and rep count instructions. The regulars seemed to have it down though. You can get away with doing your best (thats what counts). Did not feel very welcome, but it was a great workout.
Killer X Training with Jorge
Great instructor! So sore the next day.
Killer X Training with Jorge

Killer X Training with Jorge
Class was awesome -2 stars for the horrible prison bathrooms
Killer X Training with Jorge
intense HIIT circuit training. great work out. there are folks in the class who move much faster thru the circuits so just try to stay focused and don't get distracted
Killer X Training with Ben
Motivating
Killer X Training with Ben
Instructor gives too many instructions to follow at once. He will say do W, X, Y, Z for the next 5 mins. All with different rep amounts, very confusing. Also, there is no attention to form. I saw many people who were going for quantity over quality of the reps. I probably won't be back for this class.
Killer X Training with Jorge
Weird class in the middle of the large open gym.
Killer X Training with Ben
Great workout. I wish some of the circuits were written on the mirror because it's hard to remember everything so I felt like I was constantly trying to see what others were doing instead of focusing on my workout
