What Time Is Best For Anabolic Growth?

Does it really matter if you workout in the morning or evening?

Hormones such as insulin-like growth factor, testosterone, insulin and growth hormone, critical promoting protein synthesis and muscle growth. 

While levels of catabolic hormones (which cause the metabolic breakdown of complex molecules into simpler ones) like cortisol inhibit training gains. The strength of protein signaling also influences the amount of muscle growth.

Hormones and signaling chemicals vary during the day. This may affect muscle responses to weight training. A study from Metropolitan University in the U.K. found discovered the affects on anabolic muscle growth. The biological environment for promoting muscle hypertrophy is more optimal in the evening than in the morning. Suggesting evening workouts have potential for producing greater changes in muscle growth and strength.
