To answer that question, we need to understand how our strength at different joint angles changes after strength training.

Isometric exercise is a type of strength training in which the muscle length and joint angle do not change during the contraction.
You can't see it, but when you hold a plank or other isometric pose, muscle fibres are pulled from both ends of the contracting muscle — not just one section — meaning your body recruits more muscle fibres than if you were changing the joint angle.
This continuous change of angles and stresses along the joint will help make your ankles more resilient and better conditioned for negative stresses down the line.
Those are the kind where your muscles are under tension without changing length or joint angle.
This continuous change of angles and stresses around the joint will help make your shoulders more adaptable to strains and forces encountered in all your training and daily activities.
In vivo human gastrocnemius architecture with changing joint angle at rest and during graded isometric contraction
Planks are an isometric exercise, meaning the joint angle or length of the muscles you're working doesn't change throughout the exercise.
On the other hand, people who use an internal focus [change their joint angles disproportionally](https://www.ncbi.nlm.nih.gov/pubmed/19846388)-- some joints end up moving more than they should, while others are neglected.
Joint angle - specific strength gains at shorter muscle lengths tend to be caused by changes in neural drive (Noorkõiv et al. 2014).
The purpose of this section is to detail the muscle moment arms of the pectoralis major muscle in each of the sagittal, frontal, and transverse planes, and to explain how they change with changing joint angles.
The reason for the difference between the changes in joint angle - specific strength and the changes in joint angle - specific neural drive is that both peripheral and central factors are operating, and the impact of joint angle - specific neural drive is greater after training at short muscle lengths, while the impact of peripheral factors (like regional muscle size and / or muscle fascicle length) are greater after training at long muscle lengths.
In one study, Remaud et al. (2010) assessed joint angle - specific changes in maximum voluntary isometric contraction (MVIC) torque and in neural drive after isotonic and isokinetic types of external load, using knee extension training.
Using eccentric - only knee extension training, Guilhem et al. (2013) assessed the effect of constant load and isokinetic external load types on joint - angle specific changes in torque and EMG amplitude.
Moreover, as Németh et al. (1985) showed, the moment arm length does not change substantially with hip joint angle, as is observed for the other major hip extensors, the gluteus maximus and adductor magnus.
The length of the moment arms of each muscle also changes depending upon the joint angle.
If this is the case, we should find that the main causes of specificity in strength gains after training with different types of external load are regional hypertrophy and joint angle - specific changes in neural drive (especially at end range of motion).
After all, even if we get stronger overall, if the angle of peak torque changes, then we will find that some joint angles increase hugely in strength, while others do not improve strength very much at all.
This is in line with the expected effects of joint angle - specific changes in neural drive being most relevant at short muscle lengths.
This specificity is likely attributable to differences in regional hypertrophy (which may be a function of different increases in muscle fascicle length) and joint angle - specific changes in neural drive, just like partial and full range of motion training.
While the moment arm length appears to change relative to the elbow joint angle, the overall moment arm lengths regardless of angle joint angle appear to be correlated with the muscle cross-sectional area of the triceps and the dimensions of the bony attachment site of the olecranon (Sugisaki et al. 2010).
On the other hand, regional hypertrophy (but not always muscle fascicle length) seems more important than changes in joint angle - specific neural drive for the joint angle - specific gains in strength after isometric training at long muscle lengths (Alegre et al. 2014; Noorkõiv et al. 2014).
There are few changes in joint angle movements during the deadlift, lunge and squat that could explain the changes in the pattern of net joint moments.
The factors affecting the perpendicular force can be further subdivided into permanent factors that do not change substantially from one moment to the next (e.g. muscle size) and temporary factors that can be altered quickly (e.g. joint angle).
Variations of these movements that change angle work the muscles differently and in some cases can more beneficial and joint - friendly — dumbbell floor press, Neutral grip eccentric chin - up, Chest supported neutral grip dumbbell row, steep incline dumbbell press, B - stance deadlift, Bulgarian split squats.
Test of transfer (long - term): no trials have compared strength training using constant load vs. accommodating resistance on changes in sprinting ability, but if the band or chain resistance was set to produce a peak contract in the half or quarter squat bottom position, it might transfer as well or better than a full squat with constant load if the loading was challenging enough at that joint angle.
This section provides a summary of the electromyography (EMG) studies into how the EMG amplitude of the gluteus maximus changes with joint angle.
Muscle moment arms can often change with changing joint angle.
Wear in a non-load-bearing ball joint will cause a noticeable change in the camber, caster or toe angle of a front suspension.
This changes the manner in which the bones interact with each other, realigning the angle of the tibial plateau at the stifle joint, this method uses one of two procedures: TPLO and TTA.
Moving, or «Advancing» the tibial tuberosity changes the patellar tendon angle and neutralizes the forces on the joint.
Having nails that are too long causes a dog to change the angle of its paw and leg as it moves, potentially causing or exacerbating trouble in all the joints, right up to the shoulder or hip.
