12 week o-lifting routine?I think you are over programming. A 12 week periodised scheme is for people who are fully commited to o-lifting as their only sport, and have been lifting for a couple/few years and are squatting in the 400+lb range.I think you should do something a lot simpler, especially if their goals are broader and not o-lifting specific.Also, how long have these people been lifting, and how old? Are they back squatting above 130-140kg.If they in their mid-late teens, and squatting less than 140kg, i would have them squatting, benching, pressing, and deads, and how a power clean or power snatch as their explosive o-lift movement.Take a look at starting strength by mark rippetoe
Over-programming? Lol...I don't think any coach on this planet that knows anything about strength training and periodization would agree with you that you must be an elite lifter to perform 12 week training cycles. We have periodized programs for all the sports at our school and also do programming for golfers, baseball, football, and soccer players ranging from 10-14 years of age and they have all had great improvements in strength from these workouts. Obviously there is an age where you can start loading up the weights but still there is nothing wrong with periodization for other sports and skill levels. Every sport has an off season where athletes should get stronger and during the season they still have to maintain strength and power.
