primarily the biceps, also the pectorals (pecs), and shoulder, and abs (most of the upper body really)

I don't know what you mean by momentary muscular failure. Surely if this happens he won't succeed in lifting the barbell? Lifting a barbell or indeed any muscular work done involves chemical changes in the muscles which provide the energy required, in this case raising the weight against the force of gravity. The energy used to lift a weight m kg a height of h meters is 9.81 x m x h joules.

The primary muscle used in the barbell upright row is the deltoid, specifically the lateral or middle deltoid. This exercise also engages the trapezius and the biceps to a lesser extent as secondary muscles. By lifting the barbell vertically towards the chin, the upright row effectively targets shoulder strength and stability. However, it's essential to use proper form to minimize the risk of shoulder injury.
The barbell squat exercise primarily works the quadriceps, hamstrings, glutes, and lower back muscles.

When the barbell says 20 kg on each side, you are lifting a total of 40 kg.
Yes, the trapezius muscles are the primary muscles used during barbell shrugs. This exercise primarily targets the upper portion of the trapezius, which is responsible for elevating the shoulders. Additionally, other muscles such as the levator scapulae and the rhomboids may also be engaged to a lesser extent during the movement. Overall, barbell shrugs are effective for building strength and size in the traps.

The barbell upright row primarily occurs in the sagittal plane of motion. This movement involves lifting the barbell vertically along the body, which primarily engages the shoulder and upper back muscles. The sagittal plane divides the body into left and right halves, and movements in this plane typically involve flexion and extension.
