4-week Fitness Program

If you want to reach your full potential, you’ll need to step out of your comfort zone and push through your limits – it’s the best way to discover the best version of yourself.

During these four weeks, you’ll most likely find that your mental barriers are stronger than the physical ones but committing to this program will align your mind and body to push your limits and truly test what you are made of.

We know you’ve got what it takes but do you know what is your true potential? Let’s find out!

Please note that the information provided below cannot replace individual advice from health professionals. Please consult your physician before starting a new fitness program.

Workouts

Every week you’ll be challenged to complete 4 different workouts that will inspire you to get out of your comfort zone.

We’ll vary the sessions, both with movements, reps and time, to maximize the results. Some movements will show up more often than others as compound movements that give you the most bang for your buck with regard to burning calories but also building strength.

Strength

In the workout sessions that focus on getting strong, we’ll slow down the movements and increase the time under tension (TUT), which has been proved to elicit great strength gains. Slowing down will allow us to focus on proper mechanics, moving the way the body was meant to move and undoing the hours of sitting that most of us have to do every day.

HIIT

Focusing on HIIT means that you’ll be moving fast and breathing heavy. You’ll find yourself out of breath and with a burning sensation in your muscles - but this is where results are made, so don’t be shy to push your potential. Combining cardio and strength training will give you the best of both worlds – hypertrophy and strength gains with an increase in calories burned.

Mobility

The purpose of mobility work is to increase our range of motion and gain control of new movements. By spending time moving well and with purpose you can regain full range of motion and remove aches and pain that you may be experiencing. After all, strength alone isn’t enough, you need a full range of motion and functional muscles to be able to use your strength.

Recovery

Recovery is just as important as the training itself. If you don’t allow the body enough time to heal itself and restore its energy supplies, you won’t get the most out of your sessions. Workouts create micro damages in the muscle tissue and it is the subsequent healing of this damage that will make you stronger.

Imagine scratching a wound before it has healed – you’ll just end up slowing down the process. The recovery time between workouts depends on a number of variables, but the key components of recovery that apply to everyone are sleep, food and rest, together with time.

You can aid recovery by doing light activities to promote blood flow and movement in the damaged tissues. The blood carries the necessary building blocks to regenerate the damaged muscle tissue so an increase in blood flow during light to moderate exercise will assist recovery.

Workout instructions

Strength

Each movement is paired with another and is to be performed as a superset, meaning that every 3 minutes you perform a set of movement 1 and a set of movement 2 alternating between the sets. Once all sets are completed, you will move directly to superset 2 and complete it as superset 1. In superset 3, as soon as you have completed the first movement, you move directly to the second movement for the designated number of sets.

HIIT

You’ll perform each movement for as many repetitions as possible within the set time and then move straight to the next movement and continue in the same format. After finishing the last movement, you’ll rest for 1min and repeat it for the designated number of rounds. The bonus should be performed as a continuous effort with no rest between the sets.

Mobility

When doing mobility, you should focus on breathing well, allowing your body to relax and get used to the new positions. We will start and finish each session with a dynamic stretching routine that will allow you to “feel” the newly gained range and gradually build strength. It’s key to warm up before this session to prepare your body for the movements and make the muscle tissue more elastic and pliable.

Tempo

There’s a designated tempo for some movements in the program in the format of XXXX (e.g. 2020) which means “eccentric”, “bottom’, “concentric”, “top” portion of the movement. For example, if you do an air squat with the tempo 2020, you start moving down slowly (2sec) no pause at the bottom (0sec) and then move up again slowly (2sec) and once you reach the top, you start going back down again with no pause (0sec).

In some of the workouts, the tempo is defined as 'every minute on the minute', which is often shortened as EMOM. This means that you perform the set at the beginning of a minute and then rest until the beginning of the next minute on the clock. So for example, if you are asked to do a set EMOM for 10 minutes, you repeat the set the beginning of each minute, 10 times in total.
