William Bonac

IFBB Professional Bodybuilder, Sponsored Athlete

William Bonac is an IFBB Professional Bodybuilder and sponsored athlete from Ghana. He’s worked extremely hard to build the physique he has today. He prides himself on his confident, down to earth attitude.

This mental approach has taken him all the way to the Mr Olympia stage. He’s admired for his large legs and arms, as well as his dedication to proper nutrition – being compared frequently to the American bodybuilder Kai Greene.

It has been a long and difficult road for William in reaching this level. He makes it clear to his fans that it’s certainly not the career for every fitness enthusiast. He started training at 13 years old as a way to release stress – it took him almost 2 decades to reach the 2016 Mr Olympia stage.

With an ever-increasing social media fan base, William Bonac is a face to look out for on the professional competition circuit.

Heavy And Intense

William’s workout are both intense, and heavy. He completes sets of both free-weight exercises and machines, where he pushes his body to failure regularly. His weekly split looks like this:

  • Monday: Chest and Triceps
  • Tuesday: Back and Biceps
  • Wednesday: Rest
  • Thursday: Quads, Hams and Calves
  • Friday: Shoulders
  • Saturday: Cardio
  • Sunday: Rest Day

Focusing On Constantly Improving Legs

William admits that his legs have always been his weakest area. He now trains them extremely hard. His favorite exercise is the front squat, and values this exercise as one of the main movements of his entire routine.

He says “I prefer the front squat because the front Squat attacks my quads more than the Squat, plus it prevents me from using too much of my lower back.” He also advises people new to the exercise to never let their knees cross over their toes. He says that doing so, makes stabilizing with a straight back more difficult.

Strong Arm Workouts

Many of William’s high competition scores have come as a result of his well developed arms. He trains his triceps and biceps with his back and chest, seeing this combination perfect for spending a lot of time on the muscle individually.

Many of his fans recognize his bicep peaks as some of the best on earth. He incorporates heavy machine workouts for his biceps, and also pushes hard on dumbbell bicep curl drop sets top achieve this amazing feature.

William values the barbell curl in particular for his large arms.

In terms of tricep exercises, William does a lot of tricep pushdowns. He likes this exercise due to the predictable movement it offers. Additionally, he completes tricep extensions, dips, and a variety of other machine based exercises.

Buying In Bulk

William buys his own food from his local market in the Netherlands. He does this because he can buy a lot of meat and eggs for half the price, compared to his local supermarket.

Every fortnight, William does one large shop that sees him through the next two weeks. He does this to make sure he’s always got enough food at home for recovery, and pre-training meals.

Healthy And Nutritious

Once he’s bought and stored all this food, he prepares his own meals in advance and stores them in small Tupperware containers.

He loves to eat lean fish and meat, with rice and potatoes and other healthy carb options. He also buys a lot of eggs, so he regularly makes omelettes for breakfast, or eats them boiled.

A daily meal plan which William follows regularly is below:

  • 1st Meal  – 100g of cooked oats, 3 whole eggs, 3 egg whites and 1 scoop of whey, with almonds
  • 2nd Meal  – 175g chicken, 1.5 cups of cooked white basmati rice, vegetables and more almonds
  • 3rd Meal  – 175g chicken, 1.5 cups of cooked white basmati rice, a selection of green vegetables and almonds
  • 4th Meal  – A pancake with 100g of cooked oats, 1 whole egg, 5 egg whites and 2 scoops of whey protein

Idols and Influences

Flex Wheeler was one of William’s favorite bodybuilder’s growing up. When he was in his twenties, it was Kai Greene who really caught his attention, and inspired him to compete.

As well as these legends, he is also inspired by his own journey.

You inspirational my man.
You have won it where it’s almost impossible to.
Keep on keeping on brother Africa is with you.

Congratulations on reaching 2nd place at the Arnold Australia March 17, 2018. You had more definition on your back and biceps than Roelly. But the latter must one admit, was massive. I am nonetheless very, very, very proud of you, my brother.

His meal plan is very small I don’t know how he could be that big eating only that as i eat more than that and I’m now where close to him in size

Hi, William am proud of you since you came to Kenya, you are a nice down to earth guy, I hope one day to receive a William Bonac branded belt since I have began my training, also you could consider opening a gym in Kenya or in Africa to help keep the youth free from pressures of alcohol and drug addiction. I also take this opportunity to congratulate you on your second Arnold Classic win.
