So I've been reading a little about low rep vs high rep training and found some contradicting opinions on that. Appearently high reps (if performed until failure, can stimulate muscle as much as low reps (with more weight). Does that mean that higher reps could be as effective or at least close to the level of effectiveness of that middle rep range for hypertrophy, or is it just a non-contest?
Yes high reps CAN be effective for hypertrophy. You should try it out for AT LEAST 2 months(hypertrophy is a slow process!) and take pictures/videos before and after and see what happens. some muscles like quads, delts, calves are known to respond better to high reps for many people(doesnt apply to all people of course). one obvious drawback on high reps is , its harder to progress in weight. One advantage is, its easier on the joints and you have more awareness of the muscle/s being used.
You can also try to mix different rep ranges. for example you start with lower reps and finish off with higher repetitions(this is recommended by the most, because you can progress on the weight with the low rep stuff and then concentrate on the pump on the accessory).But you can also try to start out with high reps to get a pump and therefore have more blood in the muscles and then start doing exercises in the lower rep range(or any other scheme). since progressive overload is not the only tool in bodybuilding you can experiment a bit. Just remember to take pictures and compare them, because muscle gains come very slow!
