Quote[/b] ]1.3 Scheduling of HST Phase and Sections
As mentioned before, I prefer layering in the techniques according to each phase. More or less, this is the general template (though there are exceptions.)
Note: Because of this layout, most isolation movements are not performed during 15s. This is intentional.

3.1 Specialization and Metabolic Stress Terminology
Below are some terminology you will see again and again in the Specialization section. Again, some of the explanations are getting a little ahead of their proper sections in this document, but it’s probably better to get exposed now before you get bombarded with it later.
3.1.1 Stretch point exercise vs. Peak Contraction exercise
These are Position of Flexion-related terms. Essentially, stretch-point exercises are exercises that work the target muscle through a particularly stretched range of motion. Usually the sticking point is at the point of full stretch. They increase strain through stretch and increase MAPKp38 activity and accelerate sarcomere hypertrophy. Most stretch-point exercise is single-joint, isolation movements with the exception of legs (SLDL, sissy squats.) Peak-contraction exercises are exercises that work the target muscle in its most contracted range of motion. Virtually all peak-contraction exercises are isolation movements. These don't increase strain that much over normal compound movements, but they do a great job at increasing metabolic stress, fatigue, MAPKerk1/2 activity, and sarcoplasmic hypertrophy in the target muscle. Most of y'all been doing this movement for years. There are POF tables detailing a sample of them. Note: certain movements can "qualify" as both, but the actual technique does vary whether you want to emphasize the stretch or the contraction.
3.1.2 Static hold vs. Loaded Stretch (LS)
Static hold is just holding the weight at a certain position. Your static strength is greater than your concentric strength, though less that your eccentric strength. Static holds let you milk the benefits of the muscle's contracted or stretched point and can be way to extend the TUL of a set. Loaded stretches are essentially static holds in an extremely stretched position. When a mildly heavy-to-heavy weight is held in an unusually stretched position for sufficient time, the passive-stretch reflex kicks in and slowly increases the effective tension at that point. Natural application of loaded stretch is to simply perform a static hold with your stretch-point movement at that load. That facilitates a progressive element with loaded stretches. A more thorough discussion is covered in the respective Customizing section.
3.1.3 Partial vs. Pulsing
Partials are about performing a rep in a limited range of motion. You can't use as much weight as you would with a static. However, you introduce concentric and eccentric motion. Various applications exist in using partials to accentuate strain and accentuate metabolic stress. A more thorough discussion is covered in the respective Customizing section. Pulsing are essentially partials with very short ROM (like 1-3 inches.) Pulsing with peak contraction exercises is perhaps the most effective way to generate metabolic stress. A variation of pulsing, by hitching the myotatic reflex, exists in order to accentuate strain as well. A more thorough discussion is covered in the respective Customizing section.
3.1.4 Pulses vs. Pulse Stretch (PS)
Pulsing is a form of generating high metabolic stress. It involves working at the ROM near contraction.
Pulse stretch is a form of generating extremely intense stretches. It is a variation of ballistic/PNF stretching and is arguably the most effective and dangerous technique to generate strain.
PS is “bouncing” at near stretch. That is, as the weight approaches lockout, suddenly “slack” the weight to rapidly increase the speed of the descent. Then, suddenly change direction, raising the weight. When this occurs, an intense contraction should occur. As soon as this happens, lower the weight, stretching against this contraction.
3.1.5 Rest pause
Ideally, you'd hold the barbell in its locked out position until you can do another rep. But, what I espouse (for boosting metabolic stress) is a combination of rest-pause and a steady progression of normal, then partial, then pulse, then finally static movements in order to extend TUL.
