However, for optimal results, you might want to consider alternating between different rep
ranges in order to force different types of
muscle cells and
fibers to grow.
This, of course, decreases the effectiveness of the exercise, since the limited
range of motion will reduce the number of
muscle fibers recruited, so why would you want to do it?

Since these three exercises have complementary strength curves, by grouping them (or any other three exercises which offer high tension at different parts of the
range of motion) in a bicep tri-set, you will enable maximum tension throughout the entire
range of motion, activate all available
muscle fibers and get a truly incredible pump.

muscle fibers react to high rep training in
ranges of 12 — 20 repetitions per set.
The majority of studies seem to support the claim that the dumbbell bench press is a better option for anyone looking to increase his chest size, mainly because of the greater
range of motion involved — a greater
range of motion on pressing movements means more horizontal flexion and adduction and a greater recruitment of chest
muscle fibers.
Therefore, in order to achieve maximum gains, you need to utilize different rep
ranges that will activate both types of
muscle fibers: use heavy - load, low - rep training as your primary style but also throw in a couple of sets with lighter loads for more reps.
For those who of you who are not familiar with intensity - boosting techniques, partial reps are basically reps done in a specific
range of motion, for example, performing only the top six inches of the full
range of motion of a bench press, and can help you yield more rapid
muscle gains by overloading
muscle fibers.
Generally speaking, the greater the
range of movement you move through when doing an exercise, the greater the
muscle fibers it will work and the more effective it will be.
Stick to proper form and higher repetition
ranges (15 - 20 reps) in order to train the nervous system to activate the
muscle fibers.

muscle fibers in order to maximize a player's
range of motion.

range of motion of an exercise instead of changes in resistance, in order to target those different
muscle fiber types.
Aiming to improve your physique this information becomes very valuable, it enables to choose the optimum training (training types, their balance, the specific
range of reps and rest trying to affect different
muscle fibers, unique exercises to work the particular
muscle groups etc.) and diet plans (adjusting energy intake, nutrients etc.).
On the other hand, the gastrocnemius comprises a mixture of type I and type II
muscle fibers with a slight tendency towards a greater proportion of type I
muscle fibers, with the proportion
ranging between 50 — 76 % (Johnson et al. 1973; Edgerton et al. 1975; Dahmane et al. 2005; 2006; Keh - Evans et al. 2010).
The rectus femoris displays a slight tendency towards a greater proportion of type II

But the broad
range of contractile properties across all
muscle fibers means that
fibers of the same type do not all have the same level of strength, endurance, or speed.
From what I understand your theory is that training with variety of rep
ranges / weights in the same workout leads to greater overall
muscle fiber fatigue and therefore adaptation?
This chest training technique actually creates an isolated
