關於 biceps exercise ，我們在網路上蒐集到這些相關的討論、資訊與評價

【主動不足（active insufficiency）】
.
當肌肉長度在「過度縮短」的位置，會使肌肉能「主動出的力減少」，這樣的現象我們稱為主動不足（active insufficiency）。因為肌肉的收縮，是倚賴肌凝蛋白（myosin）跟肌動蛋白（actin）的結合，我們稱為橫橋（cross bridge），橫橋（結合）的數目越多，能產生的力越大。當肌肉處在過短的位置，會使肌凝蛋白跟肌動蛋白彼此蓋住，所以形成的橫橋會較少。
.
這也是為什麼，許多動作跟姿勢，肌肉會處在相對「中間」的位置，稱為肌肉的休息長度（muscle resting length），既不是縮短、也不是拉長，因為能形成的橫橋是最多的。
.
🔸 生活的應用
因此大多數人，提著重物時，手肘會不自覺地彎曲到90度、呈一個直角，因為這是肱二頭肌（biceps brachii）的休息長度，能主動產生的力最大。
.
🔸 訓練的應用
訓練中，「同一個動作下，可能用許多肌群」，如果想要著重在其中一個肌群，可以將其他肌群擺在較短的位置，來減少他們的使用。例如橋式（Bridging）可以同時用到臀部跟大腿後側肌群，若傾向用更多臀部肌群，會透過增加膝關節的彎曲角度，使大腿後側肌群處在較短的位置，來達到主動不足。

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

Most people who've been watching YouTube for years would understand this. If you're unhappy and get triggered by this, well, this channel isn't for you then. I’ve provided free workout schedules and programs since day 1 and have always optimised my meta data as such so that's not going to change.

Having said that, it doesn't mean the workout do not work. You will still see results by following a suitable program schedule, watching your diet, being in a deficit or surplus (based on your goals), doing exercises in good form, etc. These are all equally important factors. You're not going to get abs, grow a booty, grow biceps magically from 1 or 2 videos, in 1, 2, 3 or 4 weeks cause everyone is different. I've explain multiple times throughout videos throughout my channel over years that it takes time and lots of factors, so don't take a video title out of context. Targetting fat loss is not scientifically proven. Everyone is different and it takes time.

When doing any home workouts, do take precaution to exercise in a safe environment, and if you need help or you're not seeing results, I suggest seeing a health and fitness professional to give you tailored advice on your exercise form and dietary needs.

15 Mins Legs and Booty workout with Dumbbells, that you can do with or without a resistance bands. Time to get fit if you have a set of dumbbells at home, feel free to use alternatives you can find at home if your just getting started.
