How Long Does It Take to Build Forearms?
In the bodybuilding world, a well-known maxim is that strength comes before size. To build muscle, strengthening will have to come first. This fact applies to all muscles, including those of the calves, legs, chest, arms and especially forearms. Unlike other muscles of the body, the forearm muscles usually take longer to grow in size. The exact time frame it takes to develop your forearms, of course, will vary widely depending on factors, like your specific goals, training regimen and self-discipline. With proper resistance training, however, you should begin to see some results within a few weeks, according to the University of New Mexico.
