Strength training is not only associated with an increase in muscle mass, but also an improvement in the nervous system's ability to recruit muscle fibers and activate them at a faster rate. [88] Neural adaptations can occur in the motor cortex , the spinal cord, and/or neuromuscular junctions .
The deadlift is a very effective compound exercise for strengthening the lower back, but also exercises many other major muscle groups, including quads, hamstrings and abdominals. It is a challenging exercise, as poor form or execution can cause serious injury. [8]

The barbell back squat Bodyweight squat. A squat is a strength exercise in which the trainee lowers their hips from a standing position and then stands back up. During the descent, the hip and knee joints flex while the ankle joint dorsiflexes; conversely the hip and knee joints extend and the ankle joint plantarflexes when standing up.
Bridging exercises are done with a flexed knee to lessen the stretch on the hamstring (a knee flexor) and focus the hip extension work on the gluteus maximus. In that same respect, the reduced knee flexion makes plantar flexion work comparable to a seated calf raise, due to the lessened stretch on the gastrocnemius (like the hamstring, also a knee flexor).
Open chain exercises are postulated to be advantageous in rehabilitation settings because they can be easily manipulated to selectively target specific muscles, or specific heads of certain muscles, more effectively than their closed chain counterparts, at different phases of contraction.
