Testosterone is a hormone that is produced in large amounts by males (and a little bit in females), in the testes and adrenal glands. High testosterone levels are associated with sexual performance, reproductive function, muscle mass, hair growth, aggressive, competitive behaviors, and other such manly things. Testosterone levels tend to peak at the age of 40, and slowly decline from there. Luckily, there are many things you can do to increase testosterone, so if you feel like your T levels could use a boost, you've come to the right place.
When it comes to resistance training, both short-term and long-term research has shown that higher-volume training programs (think multiple sets at a moderate to high loads—70 to 85 percent of your 1 rep max) tend to elicit the greatest hormonal response. 1,13 Stick to protocols that stress large degrees of muscle mass and are moderate to high intensity. Additionally, more seasoned gym goers may want to incorporate forced repetitions periodically into their programs, as testosterone increases have been observed with this type of training. 14 Incorporating other post-failure training techniques such as dropsets or partials may similarly be associated with higher T production.
