high rep calf raises is just a great way to completely fatigue every MU, i can't seem to do it with low rep calf raises, not one bit.. my calfs will feel dead but i'll feel i have alot more left in the tank, hard to explain.. with high rep calf raises, they are completely fatigued and I feel i tapped into everything I possibly couldbut the gastrocs are about as fast twitch as the glute max.. both respond very well to moderate-high rep training.
I know what you say about high rep calf raises, and I feel the same. But aren't the gastrocs kind of 50-50 in terms of fiber content (fast twitch/slow twitch)? I knew the glutes are 60-40 in favor of fast twitch, and hamstrings 70-30 (obviously, with individual-related variations).
people who are afraid of volume make less gains.. for example, how many impulses do the glutes get during a 100m sprint? quite a bit, say 24+ "each glute".. hard to develop the glutes maximally just sprinting 20's, you need to fatigue them to the max, which happens in a 100, but if you don't sprint those kinds of distances, you need to fatigue them max in the weight room using the same principles, using volume.. they get stronger much quicker when placed under fatiguing volume work... so do the calves.. so does pretty much everything honestly lol.. volume work is pretty important and alot of people are afraid to do it because of the misconceptions in s&c.
I think it all comes down to common sense. If you use cycles of training and have different periods where you want performance, and periods where you can afford more volume, you can plan that accordingly.
For example, I jump a lot in the Summer because I play ball in the park. But in the Winter I don't have any place to play ball so my volume of squatting etc goes up quite a bit.
