I like to do four sets of eight reps of biceps curls.

我喜欢做四组头肌弯举，每组 8 次。

Some muscles are familiar to us, like the pectorals and the biceps.

有些肌肉对我们而言更为熟悉，比如胸肌和头肌。

Milo has biceps. - Biceps. - Tenosynovitis. - Tenosynovitis.

麦洛有头肌。— 头肌。— 腱鞘炎。— 腱鞘炎。

First, researchers took the circumference of 61 men's and women's biceps, measured their grip strength, and their height.

首先，研究人员测量了61名男头肌周长，们握力和身高。

And my biceps are at least better than Alex's.

我头肌至少比亚历克斯壮。

So the biceps will shorten while the triceps will lengthen or relax, pulling up the arm and making it bend at the elbow.

所在三头肌伸展或者放松时，头肌就会收缩，完成胳膊举起，向着手肘弯曲动作。

Those muscle fibers then form larger, string-like bundles called fascicles, which combine to form the larger rope-like muscle organ, like your biceps brachii.

这些肌肉纤维然后形成更大、像绳子一样束，叫做束，它们结合在一起形成更大像绳子一样肌肉器官，就像你头肌。

I suddenly realized, the strengths that I had in my arms and biceps was not actually enough for me to look even fit because it is disproportionate growth.

我突然意识到，我手臂和头肌力量实际上不足让我看起来更健康，因为它是不成比例增长。

After eight weeks of grueling training, it was shown that lifting in the initial ROM from bottom to 68 degrees was clearly more effective than lifting in the final ROM, yielding significantly greater biceps muscle growth and curling strength.

经过八周艰苦训练，结果表明，在初始 ROM 中从底部提升到 68 度显然比后半程 ROM 更有效，头肌生长和卷曲力量明显更大。

Each one of your different skeletal muscles — like your biceps brachii, or vastus lateralis or gluteus maximus — is technically its own organ, made up mostly of muscle tissue, but also of connective tissue, blood vessels, and nerve fibers.

你每一块不同骨骼肌——比如头肌、股外侧肌或臀大肌——严格来说都是自己器官，主要由肌肉组织组成，但也由结缔组织、血管和神经纤维组成。
