How should i workout to keep cortisol at bay and gain muscle and testosterone side by side ? thanks

Autoregulation: Hi. Unless you have a rare disease, your cortisol and testosterone will be regulated and kept normal automatically under the exquisite control of the hypothalamus and pituitary. You don't have to worry about it. They're on autopilot and right where they're supposed to be. Eat healthily, exercise regularly, and don't smoke. Good luck!
