Place the thighs on the padding and fix the feet in the holder (feet pointing downwards). Make sure that the support pad is adjusted so that the hips are free and the legs are straight. The hips are extended, the exposed upper body is kept horizontal and the arms are held on the chest or crossed. From this position, lower the upper body, first lowering/tilting the chin towards the chest before starting to bend the spine in the neck. The upper back is then rolled up, followed by the lower back. Finally, the hips are flexed and the spine is briefly stretched. Once in the end position, the hips are stretched first in reverse order, while the spine is flexed. The hips remain stretched as the lower back and then the upper back are stretched. With a neutral spine and stretched hips, return to the starting position (upper body horizontal to the floor).

Caution:
Consciously curl or uncurl your back vertebra by vertebra.

Every person has an individual perception of pain. That's why it's important to find out the right impact hardness with your partner first. During the sensitisation exercises, you learn to trust your partner.

• Participant A: stands still in the boxing position and gives feedback.
• Participant B: attack with punch combinations 1-3, then step back (cover).

• Participant A: stands still in the boxing stance + 1x counter punch
• Participant B: attack with punch combinations 1-3, then step back (defence)

• Participant A: stands still in the boxing stance + 1x counter punch and step back (defence)
• Participant B: Attack with punch combinations 1-3, then step back (cover) plus counterattack (step forward)

• Participant A: Punch with lead hand to head
• Participant B: Dodges and strikes with lead hand to stomach region

Recognising punch hardness in Light Contact Boxing:
Feedback from opponent (feel), facial expressions (see), punch (hear).

Participant:
1 pair of boxing gloves

Fight 1 vs. 1, whereby the participants are assigned the following tasks:

• Participant A: attack with combo, block, counterattack
• Participant B: block, counterattack, block

Before the fight begins, participant A stands in front of the mat and begins to execute as many punches as possible against the mat on the command "box". The subsequent fight thus begins for him in a fatigued state (fatigue inhibits punching hardness).

1 minute of mat punching + 1 minute of fighting = 1 round (per person)
Each participant should complete 3-4 rounds.

Variant:
Both participants punch the mat at the same time before they start fighting each other (both participants in a fatigued state).

1 soft mat (large)
1 stopwatch

Participant:
1 pair of boxing gloves

From a standing position, touch (an immobile target) in a controlled manner: Participant A puts his hands behind his back, participant B touches him with light blows to the stomach, shoulder and forehead. Participant A tries to keep his eyes open and gives feedback if the blow was too strong or missed.

Participant:
1 pair of boxing gloves

Touch a moving target in a controlled manner from a standing position. Participant A puts his hands behind his back, participant B touches him with light blows to the stomach, shoulder and forehead. A tries to keep his eyes open and gives feedback if the blow was too strong or missed. The distance is constantly readjusted between the individual hits: Participant A takes two steps in any direction after each hit, participant B must follow.

Participant:
1 pair of boxing gloves

Both participants face each other in a boxing position. Competitor B touches his partner on the forehead with light blows. After participant A has felt the hit, he immediately counters by extending his arm in the direction of participant B's forehead. This verifies whether participant B immediately goes back into cover/the defence position after the blow. After some time, swap roles.

Participant:
1 pair of boxing gloves

Two punches are connected fluently: From a standing position, competitor B tries to connect two punches fluently and touch his opponent with both. After the series of punches, competitor A counters by taking one or two steps.

Participant:
1 pair of boxing gloves

Multiple punches on a moving target: Participant A holds their hands in the basic position and moves slowly and constantly in all directions, but does not actively defend. Participant B tries to touch his opponent as often as possible in succession and connect several punches. From time to time (e.g. after approx. 8 hits), participant A counters to check whether participant B is covered. After some time, the roles are switched.

Participant:
1 pair of boxing gloves

Adjust the distance to a fast-moving target and control the (punch) hardness: Participant A is constantly on the move and tries to dodge the punches from participant B using footwork. The defender gives feedback if the punch was too strong. After some time, the roles are switched.

Participant:
1 pair of boxing gloves

Multiple participants try to push themselves off the large soft mat(s). The participant who remains wins. Only pushing and pulling the opponent is allowed.

1-2 soft mats (large)
x soft mats (small)

Post structure:
For safety reasons (protection), small soft mats are placed around the large soft mats.

Working with the cross-country ski ergometer does not require any prior knowledge of winter sports, the technique is beginner-friendly and quick to learn. However, there are a few points to bear in mind: Firstly, stand with your feet slightly more than shoulder-width apart (how close you stand to the device is a matter of taste, although taller people usually prefer a greater distance in order to achieve a full arm extension at the starting point and therefore ultimately a longer stroke). The hands should also be just outside the shoulders when gripping the handles. As the handles of the device are attached to freely movable hinges, you can easily rotate them to your optimum position. The edges of the hand, including the little finger, should be placed on the thickened end of the handle, allowing more pressure to be applied. At the beginning of the pull, the entire body is stretched, only the arms remain slightly bent, the handles are now pulled downwards at an angle until the hands are just below the knees (a V-shaped curve, where the hands move sideways away from the body, is avoided). At the lowest point, the elbows are fully extended while the knees are minimally bent (comparable to the starting position of a jump). In the return phase, the body straightens up again completely, synchronised with the backswing of the arms. Lifting your heels off the ground is perfectly fine, especially at higher speeds.

Attention:
Do not turn every repetition into a squat, as this will tire your legs too quickly. Take a deep breath before each pull on the machine and keep the abdominal muscles under constant tension.

Lighten/Harden:
The intensity is controlled by adjusting the air valve. The higher the lever is moved on the scale (1-10), the wider the flap opens and the more air can flow into the bike. More air means more resistance in the initial phase of the pull (comparable to a higher pedalling resistance in the higher gears on a bicycle). It is important to find a setting at which a continuous and controlled pressure can be maintained. If the setting is too high, the air resistance initially has to be overcome with an excessively strong pull and the remaining range of motion "runs into nothing", which is a waste of energy. If you pay attention to the background noise, you will get a suitable indicator: the aim should be to achieve the smoothest possible whirring with only slight peaks in the initial phase of the pull. Most exercisers tend to over-optimise the resistance setting. As is so often the case, less is more; levels 6-7 work well for men and 4-6 for women, with exceptions for particularly heavy and strong athletes.

Variant:
The double pole technique is usually used for training, which means that both arms work in synchronisation with each other. The diagonal technique, in which the arms are used alternately, is less common but can be used as a variation. It achieves lower speeds than the simultaneous use of the arms, but is certainly suitable as an occasional training stimulus, which above all creates a healthy rotation of the spine and a strain on the lateral trunk muscles. The diagonal technique can also correct imbalances in unevenly developed back and arm muscles (e.g. after injuries).

It achieves lower speeds than the simultaneous use of the arms, but is certainly suitable as an occasional training stimulus, which above all creates a healthy rotation of the spine and a strain on the lateral trunk muscles. The diagonal technique can also correct imbalances in unevenly developed back and arm muscles (e.g. after injuries).
