When training under certain variables, lifting weights can temporarily increase the concentrations of a variety of systemic anabolic hormones, such as testosterone and growth hormone.
Based on my assessment of the literature, it seems performing exercises that involve a large amount of muscle mass, using moderate loads and rap ranges with a good number of sets and short rest intervals evokes the greatest temporary increases in anabolic hormones.
In the bodybuilding world, it’s not uncommon to see a constant tension technique being used.
Typically, this is done by avoiding locking out the joints in an exercise, resulting in the muscle producing continuous tension for the full duration of a set.
Up until recently, the scientific consensus was trending towards the idea that a full range of motion is better than a partial range of motion for muscle growth.
The length-tension relationship demonstrates that the amount of force produced by sarcomeres (the contractile units of muscle) depends on its length.
