坐姿划船Ep. 2
今次我會再同大家分享三個划船常見毛病和改善建議，如果你成日都覺得划船動作好唔自然就要留意下啦！
❌過份挺胸
這個毛病比較常見於著重「挺胸」提示的學員身上， 挺胸的提示本身並沒有問題 ， 但過份側重於挺胸提示容易會令學員使用胸椎前凸（t-spine extension ) 代償 肩伸（shoulder extension)動作， 令動作距離縮短。 所以學員應保持在背椎中位（neutral spine)的情況及保持腹肌發力的情況下進行動作 , 減少過份挺胸動作出現
❌身體擺動
比較常見使用大重量划船的學員身上 ， 如果訓練目的是進行肌肥大訓練， 學員應運用適當的技巧把最多的訓練刺激放在目標肌肉上， 而身體擺動會運用動力（momentum) ，腰部和臀部肌肉 令身體划更大的重量， 令目標肌肉（背闊肌）的所得到訓練刺激減少，訓練成效下降， 改善建議就是用輕的重量 和 保持上身穩定的情況下 令目標肌肉達至最大的刺激
❌用太多手力
常見於學員未能運用肩胛後引（scapula retraction) 和 肩伸(shoulder extension)， 而使用(二頭肌）俗稱老鼠仔帶動動作, 二頭肌在划船動作中只是協助背闊肌完成收縮過程， 而二頭肌過份收縮， 間接令肩部肌肉（上斜方肌）收縮， 俗稱（縮膊）。 改變建議是先學習運用肩胛骨後引動作，然後使用 肩伸帶動動作 減少二頭肌代償問題
Seated row common error vol.2
Throughout my exercise experience and observation from student , here are three common errors and tips I would like to share with you guys !
❌ Excessive upper arch
Often we are told to keep the chest up during pulling type exercises such as pull up , barbell row, however if this cue is being overused , student will unconsciously use the chest arch to shorten the pulling range of motion from shoulder , which also place lesser stimulus on
the back muscles. To correct the movement , it’s necessary to brace the core to prevent from any chest arch.
❌Body swing
This Usually happens in students whose row heavy, if the goal of doing the seated row is hypertrophy (muscle cells growth) , then he/she should use the most precise technique to maximise the stimulus on the target muscles, that being said , body swing will take the work load off the upper back to other area such as lower back , hips and using momentum to finish the exercise. Put on a lighter weight and row with a more stable torso to row is a way to stimulate back muscles in seated row
❌Rowing with biceps
Biceps are the secondary muscles that responsible in the (arm flexion) part of the motion , however, beginners tend to lead the rowing motion with flexing the arms, this will tense up the neck muscle (upper trapezius) subsequently. Instead, try to initiate the movement by pulling the shoulder blades back and down , then pull the elbow back (shoulder flexion), that will helps to activate more back muscle
