On the subject of "fitness" or "workout", "whole body training", "body fit", etc. there are a lot of exercise and hands-on videos on the Internet. No matter what you do, everything is better than not moving at all . I have selected specific exercises for pistol shooting and I am sure that the range will be expanded. What they all have in common is that the exercises live from participating. Just looking at it doesn't help, it's like walking a fitness trail without doing the exercises or walking a barefoot trail that you don't tread. My physiotherapist once said that exercises only make sense from 20 repetitions - so don't do many exercises in one day, but pick out 2-3 exercises and perform them sensibly and repeatedly ;-)
