Training age is the key to progress and the rate of progress, so I would always start with a good foundation program of the basics, and then add as the training gets older, you are so correct with accumulation of injuries there are things that become more difficult, for example some of my guys will not snatch due to previous injury history, but we can get them to do a one arm DB snatch or do pulls instead so we can work around injury, these programss can be used by you but I would want you to be coached in the techniques to ensure that you are using the correct technique and improving along the way, cheers, ashley
