Discover How Hormones Are Affected by Weight Training

Workout Blog:

Whether you are an avid bodybuilder, fitness guru, or everyday person trying to stay lean, weight training can have a positive effect on your body.  Besides helping to stay in good physical condition, lifting weights can also dramatically increase hormone levels, which aid in the production of muscle mass.  In fact, according to researchers from Pennsylvania State University, workouts using heavy weights and sets between three and 12 repetitions helped to boost growth-hormone production significantly.  Though elevating these levels can be positive, there is also the risk of increasing Cortisol, which is the stress hormone that can lead to improper muscle development.


These levels can increase when you overtrain sessions and don’t get the proper nutrition after your workout.  This is why it’s important to train with the right intensity. 


 In particular, high-impact lifting leads to a boost in epinephrine and norepinephrine hormone levels, which enhances blood glucose that is vital to an increase in force and energy output.  Insulin is also a hormone that is affected by the increase in strenuous exercise.  You’ll positively enhance your insulin sensitivity with heavy bouts of weight training.  For instance, in a research study, individuals from the ages of 18 through 35 participated in six months of resistance training and found that it significantly improved their glucose levels. 


During your workout, the body burns glycogen and is stored within the muscles.  The more intense you exercise, the more your insulin sensitivity is enhanced.  In addition, a high-volume resistance program versus a low-volume circuit system has higher testosterone, insulin-like growth factor-1, and reduced levels of cortisol---which typically results in improved strength, increased speed, and enhanced power.  Weight training has successfully been able to improve hormonal responses subsequent to training, and these reactions help enhance hypertrophy. If you focus on powerful, high-volume multi-joint exercises, you’ll experience an increase in hormonal levels, which will lead to strong, healthy muscles.


As you can see, weight training greatly affects hormone levels to such a degree that it will vastly improve your performance.  The impact in testosterone is evident and choosing a rigorous training system allows you to reap significant muscle gains. 


By putting a strong emphasis on a high-volume regime and proper post-workout nutrition, you’ll be on your way to a leaner physique.  If you’re ready to elevate your hormone levels, then lifting weights could be your answer.
