Try speed work. Speed work refers to a type of strength training which uses a much lower percentage of your maximal weight. Lifting weights with greater bar speed trains your stretch reflex and your ability to build momentum more quickly, as well as recruit more muscle fibers.
The amount of time you dedicate to lifting weights depends on your weightlifting experience and your training goals. Experienced lifters can endure more training stress and need a greater number of sessions to see continued improvement.
