People avoid lifting heavy weights in the gym for a number of reasons. However, it is very important that you include a four-to-six-week cycle of heavy compound exercises. Using a bodybuilding-style workout will definitely build muscle and improve strength, but it does not teach your body how to fully activate the new muscles. High intensity workouts are considered to create a neurological response in the body. This means that the body needs to activate a greater number of muscle fibres, which can only be done under relatively heavy loads. It is for this reason that sometimes you will see a smaller person blow you away with their strength. The smaller person with less muscle mass can activate a lot more muscle fibre.
Hope everyone's having a great Friday!
