After a muscle has been stressed sufficiently with high-intensity training, you must not train that muscle again too soon so that you allow for the body to respond with a compensatory build up of new muscle tissue. You can measure your progress to determine whether or not you’re allowing enough recovery time for growth to take place simply by taking note whether or not you’re stronger any time you repeat any given workout. Some people have argued this point with me and have stated that there is no relationship between muscle size and strength. If this is the case, and you don’t need to get stronger in order to get bigger, than how exactly should you go about getting bigger? By getting weaker?
To build extra muscle, you need to eat in excess of what you currently eat, and work out with weights on a regular basis. How much muscle you can gain, how quickly and with what definition is largely determined by your genetics and age. But everyone at almost any age should be able to gain some muscle and strength with weight training. Proper nutrition is a crucial element in the muscle building process.
For every person who lifts weights these days, it seems there are two who have a podcast about it. There are more bodybuilding tips promising greater strength and muscle than ever before, and along with them a ton of confusion; one buffed-up Instagrammer says lifting heavy will get you swole, while a well-known fitness personality has claimed in recent years that two 30-minute workouts per week netted him 34 pounds of muscle in a month.
