Exercise examples
Course of motion:
- Stand with slightly straddled legs
- Torso is upright and fixed
- Hold the bar in upper grip in front of the thighs
- Lift shoulders to the longest possible distance of motion
- Hold the weight for a short time
- Then lower shoulders
Breathing:
- Inhale while moving upwards
- Exhale while moving downwards
Advices of proof:
- Complete accomplishment of distance of motion
- Training weight corresponds to fitness level
- Avoid rotation of shoulders
- Avoid bending elbows
Alternatives:
- Doing the exercise behind the body
- Stretch arms forwards
- With one hand
- With barbell bar or dumbbell bar
Course of motion:
- Stand with slightly straddled legs
- Torso is upright and fixed

- Hands are shoulder width apart
- Pull the bar upwards to the collarbone - close to the body
- Elbows have to be lifted and are always higher than the hands
Breathing:
- Inhale while moving upwards
- Exhale while moving downwards
Advices of proof:
- Elbows are higher than the hands
- Easy course of motion
- The bar is close to the body
Alternatives:
- Stretch the bar forwards
- With a barbell
- In lying position
Course of motion:
- Stand with the face to the cable pull
- Legs are slightly straddled, torso is upright and fixed
- Grasp the bar in upper grip in front of the thighs
- Hold hands shoulder-width apart
- Move arms upwards to height of head in front of you
- Flexion of elbows is not changed
Breathing:
- Inhale while moving upwards
- Exhale while moving downwards
Advices of proof:
- Calm course of motion
- Keep tension
Alternatives:
- Exercising with the back to the low cable pull
- Front lifting with a barbell bar
- Front lifting with dumbbell bar (one-handed or two-handed)
- Side lifting with dumbbells (one-handed or two-handed)
- Side lifting bent in front (in standing or sitting position, on a bench)
Course of motion:
- Sitting on the padding of the machine
- Grasp the grips in upper grip
- Hold hands shoulder width apart
- Lower until hands are on the side of the head
- Press upwards until you almost reach complete stretching of arms
- Move elbows in parallel direction to the body
Breathing:
- Inhale while starting moving downwards
- Exhale after moving upwards
Advices of proof:
- No complete stretching of elbows in highest position
- No internal rotation of arm while moving downwards
Alternatives:
- Exercising freely with cable pulls
- Dumbbell press (in standin or sitting position, one-handed or two-handed)
