What would be the effect of splitting sets of exercises for one muscle group up throughout the day? For example do one set of an exercise in the morning, one at noon, and a third set in the evening? Would this be good for hypertrophy? Alternatively, would this technique be good for running(example:run 400m 10 times throughout the day)?
I know by now you already know the answer to the question, but here is my opinion: I don’t see anything wrong in this type of training approach. As long as your program is well thought from the beginning and you have taken in consideration your food intake and time for recovering. Your body will adapt to this training and you will see the benefits you are seeking. Eventually you will have to adjust your program to continue see progress and reach the results you are looking for. In the military, during the boot camp phase, the recruits do a number of evolutions throughout the day for many days. It is design to increase the physical condition (aerobically and anaerobically). After the first few days in the program, their bodies adapt to the stress and difficulty of the evolutions and are able to perform more complex ones in a more efficient way.
