You think that doing pullups as a main excercise instead of shoulder press would be okey. Something for wreslers. I also would like to add that I will have a shoulder press but more of a secondery excerise for higher reps.[/quote]
People have done the switch. The thing to remember is to include your own bodyweight in the weight calculations. Thus, when finding your max write it as the total of the weight used and your body weight, do the calculations off of that number, and then you will be loading so that you total load is the appropriate amount.
If you use a digital spreadsheet for your workouts, you could add to the calculation for it to subtract your body weight as the last step so that it will tell you what load to use, but subtracting your own weight should not be too difficult.
