All, I am currently training in Haganah, which is an Israeli combatives art. One of the types of training offered is I.P.T.T. tactical pistol training. It's typically a 3 hour class, both hands on scenario based and then a trip to the range to put the training into live fire. At the last training class I attended, while at the range we did either push ups or squats to elevate our heart rate and induce an adrenaline dump. This is obviously not the same as a violent encounter, but it did serve a purpose. After the calisthetics, we approached the line and waited for the instructor to call "threat". We then drew from concealment and shot 3 to the chest and 1 to the head. We have run similar drills before without the calisthetics, but my time and accuracy noticeably decreased on my first few cycles. It was very eye opening training, similar to the full contact knife session I just had. This is not meant to be a condition 1 vs condition 3 thread. Just about adding the physical stresses to the drill. I carry condition 1. I am trying to take as many different training classes as I can in order to determine what works best for me. These 3 hour classes are very reasonably priced to students and allow hands on training and instruction. All live fire is done drawing from concealment. For those of us that don't have access to private ranges, that alone is worth this cost of admission.
