The workout

The workout comprises of a series of pre-fatigue moves and high intensity exercises. “Repeat each pre-fatigue and exercise in order and then repeat the full circuit 1-2 more times,” says Christina. “I have chosen a rep range aiming from 8 - 20 for each exercise so you can build up to this.”

Sleekers - (pre fatigue)

Position

Step your left leg forward and lower your hips until both knees are bent at a 90 degree angles. Your front knee is directly above the ankle and your back knee is in line with the hip. Arms out at your sides with palms forwards. Your chest is lifted, neck long and gaze forwards.

Action

Raise and lower your body up and down dropping your back knee towards the floor.

Repetitions

8-20 reps on each leg.

Sleekers jump - (exercise)

Position

Start in a lunge position with the left leg in front, knee in line with the heel and the right back knee under the hip. Arms out at your sides with palms forwards.

Action

In one explosive movement, jump in the air and switch your legs like a scissors so you land within the lunge position with your right leg in front. Keep the arms in the same position.

Hot tip

You want to keep a straight spine throughout, avoiding stooping forwards.

You can modify the exercise by stepping into the lunge alternating the legs.

Repetitions

8-20 reps on each leg.

Caterpillars - (pre-fatigue)

Position

Standing with your feet shoulder width apart, spine straight and gaze forwards.

Action

Soften the knees and drawing the abdominal in, bend forwards to place the hands on the floor. From here walk your hands out so you come into one straight line keeping your back straight and neck long.

Walk the hands back towards the feet and softening the knees, return to standing.

Repetitions

8-20 reps.

Grasshoppers - (exercise)

Position

Begin standing with feet shoulder width apart, spine and neck are long with hands at your sides.

Action

From standing, squat down and place your hands on the floor in front of you.

Jump your feet back into a plank position so your torso is in one straight line. Immediately jump your feet back to your hands and from this crouched squatting position jump your body up using your arms to help propel you.

Repetitions

8-20 reps.

Pray it’s all over - (pre-fatigue)

Position

Feet are shoulder width apart, toes pointing forwards. Sit down and back into a squat position placing your weight in the heels. Your upper body tilts forward slightly, spine is neutral and your gaze forwards.

Action

From the squat position step your right leg back into a deep lunge so both legs bend to 90 degrees. Push yourself back up again into the squat and immediately lunge back on the other leg. In this exercise you don’t actually come up to standing, hence “pray it’s all over.”

Repetitions

8-20 reps.

Sprinters - (exercise)

Position

Step your left leg forward and lower your hips until both knees are bent at a 90 degree angles. Your front knee is directly above the ankle and your back knee is in line with the hip. The right arm is bent in a runners sprint position and left arm at side. Chest and head lifted, gaze forwards.

Action

Root down into your left front foot and propel your body upwards so your foot leaves the floor. As you do so kick your right leg forwards as you bring the left arm forwards to exchange the arm position helping you explode upwards.

Top tip

You can modify this exercise by stepping the leg through into a knee lift rather than jumping.

Repetitions

8-20 reps.
