Schema highlights

Reduce your chances of injuries and increase the fun in the snow. The stronger your body, the more you can enjoy the descents. You can keep up longer, with better control and have less chance of muscle pain.

Featured exercises

In this ski prep, exercises for your leg muscles, core, and stability (balance) are essential. Below we highlight 2. The rest can be found in the app!

Airplane

Probeer jij maar eens op de been te blijven met deze uitdagende oefening.

  • 1Keep your back straight (neutral back position).
  • 2Rotate from your hip and not from your shoulders.
  • 3Try to make the range of motion as large as possible.

Deadlift

Als onderdeel van de "Big 3" lifts, kan een deadlift slechts in weinig schema's ontbreken. Serieus een van de beste oefeningen voor het strekken van je heup. Je bilspieren en hamstrings doen het meeste werk en bijna alle andere spieren van je lichaam zijn actief om je skelet stabiel te houden. Echt een topper van een oefening!

  • 1Keep your back straight during the exercise (neutral back position).
  • 2Push your buttocks back while leaning forward.
  • 3Tighten your buttocks hard during the upward movement and finish upright (i.e. don't lean backward).
  • 4Your feet are completely on the ground from heel to big toe throughout the movement.

How to get seriously stronger?

There are two routes, which go together perfectly, for getting seriously stronger. Better technique makes for more efficient power transmission. Therefore, perform every repetition properly and avoid repetitions in which you fail. Next, muscle mass is the most important variable for lifting more weight. For example, larger muscle fibres in your glutes generate more power than smaller ones during a deadlift. In short, the Be Strong schedules combine specific strength training exercises (characterised by 5 reps or less and a longer rest interval) with muscle mass training exercises (6 or more reps and often in supersets combined with another exercise).

Basic principles of your workout plan: strength

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 two things:

  • When doing the exercises that require you to choose a weight, make sure you have about 1-2 reps left in the tank, unless something else is indicated. This is a leading principle. If it says 10 reps, it means that you can physically do 11-12, but still stop at 10. However – are you at rep 10 and could do exactly 4 more reps if your life were at stake? Then do 12-13 reps that set. For the next set, adjust the weight. This way, each set remains effective.

  • 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 become stronger, 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 (5-10% above maintenance). Keep in mind: even more calories than that doesn't always mean more muscle growth – but it does always mean more fat gain.

  • 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 (20-35% of total calories) and carbohydrates (remaining calories). The ratio doesn't need to be super accurate, it's okay if it varies daily.

  • 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.
