Upper body muscle builder

BUT SERIOUSLY...

The Upper Class seriously focuses on your upper body. Your chest, back and biceps get extra attention because they are back on the curriculum on day 3. From week 4, increase the number of sets and decrease the number of repetitions. Make your exercises heavier and divide your rest for serious results. Let’s get serious!

Workout highlights

Muscles only grow seriously when you work them at least 2 times a week. This schedule focuses on the upper body and you will see the results at the end of week 6.

Featured exercises

In this serious muscle building program, we choose big exercises, complemented with essential isolation exercises, to achieve as much muscle growth as possible. Below are two highlighted exercises, the rest you will of course find in the app.

Bench Press

Bench press oftewel bankdrukken, wie kent deze super oefening niet. Volgens mij behoeft hij geen introductie en staat deze oefening bij iedereen in zijn top 5 oefeningen voor borst, schouders en triceps.

  • 1Grab the bar around 1.5-2x wider than shoulder width.
  • 2During the exercise, keep your wrists straight and your elbows under your hands.
  • 3Lower the bar under control and touch it low on your chest.
  • 4Then push the bar up forcefully and bring it back over your upper chest/shoulders.

Lat pulldown

De lat pulldown is een serieus sterke oefening voor het trainen van je zogenaamde grote rugspier (latissimus dorsi). Deze oefening imiteert de beweging van een pull-up, maar dan met je voeten stevig op de grond en de mogelijkheid om het gewicht aan te passen aan jouw niveau. Naast je lats train je ook je biceps, achterste deltaspieren en de spieren tussen je schouderbladen (rhomboids en midden-traps). Een mooi alternatief voor de pull-up, vooral als je nog niet genoeg kracht hebt om je eigen lichaamsgewicht omhoog te trekken!

  • 1Pull the bar toward the top of your chest.
  • 2Perform the upward movement in a controlled manner until your elbows are fully extended. Note, try to keep your shoulders low.

Basic principles of your workout plan: Muscle Building

Your body won't change until you seriously challenge it. This workout schedule certainly does that, but only if you commit to it. All you need to do is commit to the following three things:

  1. Try to perform the exercises to the best of your ability. Technique is more important than weight.

  2. Unless another weight is indicated, choose a weight that allows you to finish the number of repetitions prescribed. Moreover, make sure you can do every final repetition safely on your own. Does it say 10 reps and you find that you can only do 8, or go as high as 12? Then do 8 or 12 reps and adjust the weight for the next set. This sounds trickier than it is. You’ll have found the right weight after a few tries and after that, the app will remember it for you.

  3. As your muscle mass grows, you'll be able to lift more weight. In order to keep challenging your muscles, the goal throughout the schedule is to continue to (slightly) increase the weight of the exercises.

Just to eliminate any doubt; when doing exercises with your own body weight, just do the number of reps indicated. Do you see 'max reps'? Then that literally means as many reps as you can do.

How serious are you really?

Let’s be serious. Muscles don't grow without a strong nutrition plan. If you want to get seriously muscular, you will have to eat a little more than your body requires. Although there is no best ‘diet’ for everyone, the basics are usually the same:

  • Create a small calorie surplus (10-20% above maintenance). This means that, if your weight is stable at the moment, you're going to increase each meal by 10 to 20%. Just keep in mind: your muscle will not necessarily grow faster if you eat even more than that!

  • Try to consume about 1.6 to 2.2 grams of protein per kilogram of body weight each day. Spread this out across at least 4 meals.

  • Experiment with different ratios of fats and carbohydrates. The ratio doesn't need to be super accurate, it's okay if it varies daily. Easy peasy.

  • Focus on natural nutrients rich in vitamins, minerals and fibre.

  • We know this is a toughie but, avoid high-calorie, ultra-processed foods whenever you can. These include candy, cookies, savoury snacks, chips, pizza, chocolate, pastries, sweet dairy drinks, sodas, and sweet breakfast cereals.

  • Drink plenty of water, black and green tea and reduce your coffee intake.

  • Make sure that you are able to stick to your diet!

For specific questions, or to create a personal nutrition plan, we always recommend that you contact a qualified (sports) dietitian. Never change your entire nutrition plan by yourself. Seriously.
