The god thing is that in this video Jonathan from the Institute of Human Anatomy explores the science behind enhancing strength and how it can be accomplished without increasing muscular size (hypertrophy) vs strength gains that come along with hypertrophy. You can learn how this process starts in your brain, travels through nerves, and ultimately affects the muscles in your body, as well as the incredible physiological adaptations that result in strength gains. Whether you aim to improve strength without bulking up or seek to understand the intricate processes behind muscle function, you will learn the proper training protocols to achieve this. It's going to be a "heavy" one, video and training!
- 00:00 - 00:56 Intro
- 00:57 - 01:33 Why would you NOT want to gain muscle? Justin is explaining relative strength
- 01:34 - 2:02 What is muscular strength?
- 02:13 - 03:24 The motor cortex: how your brain sends signals to your muscles
- 03:25 - 03:58 What is a motor unit?
- 03:59 - 04:47 Motor unit recruitment & how this relates to strength
- 04:48 - 06:40 Improved motor unit recruitment & synchronization = more strength
- 06:41 - 08:43 Synaptic connection: the neuromuscular junction & its role in improved strength
- 08:44 - 13:23 Inside of a muscle fiber: how a muscle fiber actually contracts - the sarcomere
- 13:24 - 14:54 Changes within the sarcomere that improve strength
- 14:55 - 15:25 Another strength improvement: slow and fast-twitch muscle fibers
- 15:26 - 15:58 Training protocol: high quality and high intensity sets
- 15:59 - 16:38 Training protocol: recruiting more motor units - speed of the lift
- 16:39 - 17:54 Rest / Recovery, progression, and deload
- 17:55 - 18:47 Limitations of Improving strength without size
