I've been getting lots of requests for fullbody workouts with loads of different exercises to really get those muscles working in a relativelyshort time.

So here we are.

We're going to do a high intensity workoutwith 20 different exercises working for 35 seconds and resting for 25 seconds.

I will always give you variation options sothis is going to be suitable for all levels.

Grab a bottle of water, a mat to be more comfortableand let's get sweaty.

Alright so let's start with the first exercise.

The high knees.

Let me set the timer for 35 seconds.

Give me some speed and lift up your kneesstarting now.

High knees.

Stay nice and tall.

Big range of motion with your arms.

Also with your knees.

And speed! It's a great exercise to warm up getting ourmuscles warm.

Come on.

10 more seconds to go.


That's it, shake it out.

25 seconds of rest.

I will show you the next exercise.

It's the mountain climbers.

So we do a similar movement lifting up theknees as high as possible.

But on the floor.

So your hands are underneath your shoulders.

One straight line.

Try to not hyperextend but stay in one straightline.

And then bring up your knees in the directionof your chest.

Ready? Let's go! You decide the rhythm.

Keep on breathing regularly.

And pull your knees up.

Try to stay in one straight line.

Your shoulders on top of your wrists and thelast 10 seconds.

Keep on moving.

Give me some speed here.

And well done.

We continue on the floor with the swimmer.

Lay down, face down.

Lift up your legs, lift up your upper body.

Your thumbs are pointing out.

Pull your elbows towards your upper body, stretch your arms, come back forward.

Pull down, stretch and forward.

You still have some rest.

Ready? Let's start.

Pull back, and stretch forwards.

So squeeze your lats, your rhomboids, themuscles in between your shoulders together and also the glutes to lift up your legs andthen swim back and forward.

Your head is in extension to your spine facingdown.

A great exercise for the back, shoulders andglutes.

And last one, well done, rest.

We continue with the in and out push ups.

You can do it on your knees or with straightlegs whichever is easier.

So in and out.

So we start with the narrow grip and opento a wide stance.

The most important is that your elbows arealways pointing backwards.

Alright, let's start.

You do it in your rhythm.

Try to pull your belly button inside so youstay in one straight line.

And then while we are narrow we work a loton our triceps and while we have a wider stance we work much more on our chest muscles.

Most important is just that the elbows arepointing backwards.

So we don't put too much pressure on our shoulders.

Push through.

Last one.

Well done.

25 seconds of rest.

And we will continue with the side step squats.

So we start in the squatting position.

And do a side step, squat back.

So the whole time we stay in the squat position, hinge back, straight back, knees pointing in the direction of your feet.

In this position and we move.

Low and low.

So the lower you go, the harder it will befor your quads.

Keep on breathing and stay in one horizontalline.

Always watch your form, watch your knees thatthey point in the direction of your feet, and keep it low.

Last seconds good.

We go down on the ground again and we continuewith an exercise for our glutes.

It will be the single leg raises.

So lift up your pelvis and from here, up anddown.

Up and down.

Relax your shoulders, come into a comfortableposition.
