Back workout

Bonac trains back twice a week. One day focuses on width while the other session focuses on thickness. The following workout is for thickness. 

• T-bar row: 5 sets x 8-15 reps
• Seated low row machine: 5 sets x 8-15 reps
• Seated row machine (wide grip): 5 sets x 8-15 reps
• Low row machine: 5 sets x 8-15 reps
• Seated cable row: 5 sets x 8-15 reps
• Barbell bent-over row: 5 sets x 8-15 reps
• Deadlift partial reps: 8-15 reps

Biceps workout

William Bonac has some of the most impressive arms in bodybuilding and arguably all-time which he actually measured in January. Turns out he had 57cm/22.4inch arms which is monstrous. Here’s what he does to grow his pythons!

• Dumbbell biceps curls: 5 sets x 8-15 reps
• Dumbbell concentration curls: 5 sets x 8-15 reps
• Seated curl machine: 5 sets x 8-15 reps
• Machine preacher curl: 5 sets x 8-15 reps

Chest and triceps workout

Heck, we’ll throw in a recent chest and triceps workout that Bonac did after the Arnold Classic too since these are some of his strong points as well. 

We’d also like to add that he gave three tips for maximizing chest development. The first tip is to focus on the movement and not the weight until you learn the proper technique… “just try to focus on the movement, the technique is the most important, the weight that will come later” he explained before the session.

His second training tip is to keep the shoulder back to avoid pressing with the shoulders, especially when you reach fatigue. Then the last tip is to hit the chest from all angles for full development. 

Bonac’s favorite chest exercise is the dumbbell close-grip press which is really an amazing exercise for getting a great contraction and it’s also a good tricep developer as well. 

Alright, now for the workout. 

Chest

• Incline dumbbell flys: 4 sets x 8-12 reps
• Flat dumbbell press: 4 sets x 8-12 reps
• Incline close-grip dumbbell press: 4 sets x 8-12 reps
• Incline Smith press: 4 sets x 8-12 reps
• Cable flys: 4 sets x 8-12 reps

Triceps

For triceps, Bonac explained that it’s very important to feel a connection with your triceps. Therefore, it’s best to start light and then gradually build up the weight but not at the expense of proper technique. 

• Tricep triangle pushdown: 4 sets x 8-12 reps
• Tricep rope pushdowns: 4 sets x 8-12 reps
• Tricep single-arm cable pushdowns: 4 sets x 8-12 reps  

Diet and Nutrition

Bonac did a full day of eating 7 weeks out from the 2020 Arnold Classic. He stores a lot of meats and his wife preps his meals for him to have throughout the week. His diet is rather simple too of which he often just eats the same things. If you’re familiar with meal prep then you’ll understand how efficient it is to stay simple.

We’ve provided the details for his meal regime below. 

Meal 1

6 egg whites and 2 whole eggs w/oatmeal, banana, two scoops of whey protein

Meal 2 

300g Basmati rice, 220g chicken breast, 75g broccoli 

Meal 3

300g rice, 220g chicken breast, and 75g broccoli

Meal 4 

300g rice, 220g steak, 75g green beans

Meal 5

300g rice, 220g Salmon, 70g broccoli

William Bonac and Coach Neil Hill

William Bonac was coached by the famous Neil “Yoda” Hill who is also the coach of many big names such as Flex Lewis, Roman Reigns, model and Ryan Terry, Steve Laureus, Jon Delarosa, Alex Cambronero, Cody Drobot, and Mike Sommerfeld. 

Hill worked with Bonac during his rise to stardom, however, things got pretty sour between the two when Bonac fired Hill after he said that the latter took a large percent of his winnings. Consequently, the two went back and forth after Hill responded, and let’s just say they don’t have the same type of relationship anymore. 

Bonac said that he’d be better off alone of which he did end up doing just fine, achieving the best Olympia finish of his career last year. Not to mention, he won the 2020 Arnold Classic. So, it’s going to be interesting to see how he comes into the 2020 Mr. Olympia competition. 

But there’s no doubt he’s going to place in the top 5 as he usually does, bringing great symmetry and conditioning.
