Sebastian Mansla

Sebastian “Seboss” Mansla is a German physique champion, fitness model and sponsored athlete. He’s a popular figure on social media who is passionate about living a healthy lifestyle, as well as travelling as much as possible.

Sebastian has made fitness and bodybuilding his sole passion, but this wasn’t always the case. In fact, when he was a young adult it was boxing that attracted him. He spent a number of years in his local boxing gym learning how to fight, but he loved the strength training side of the sport so much, that he considered quitting boxing and taking up weightlifting.

In a twist of fate, Sebastian suffered an injury while fighting which forced him to quit. He immediately saw this is as an opportunity in disguise, beginning a serious strength training program immediately and embracing the bodybuilders lifestyle.

Today, Sebastian is a successful athlete and physique champion who has never stopped developing his physique since his boxing injury. He’s attracted high-profile international attention from leading fitness brands. This is his story:


 

“I think you must first want it badly, if you don’t, you are not going to stay consistent.”

Nutrition

Creating A Healthy Diet

Sebastian is dedicated to eating as healthy as he possibly can, “respecting our planet” through eating only organic produce. He tries to stay cut all year round, but when he does need to add muscle through a bulk, he does it very naturally and slowly, “respecting his body” and metabolism.

Sebastian says “with nutrition it’s a daily process… I plan everything 3 months ahead”. He also plans his meals well in advance of eating them, so that he doesn’t have to worry about preparing them on the day. This way, he can dedicate himself completely to his workouts.

All of Sebastian’s meats are lean and organic options. He eats chicken, turkey, beef, fish and game – focusing on the finest quality, freshest produce he can source.
