1 . People refer to never forgetting how to ride a bike or throw a baseball as examples of “muscle memory”, the result of a motor learning.
Previous research has shown that the changes actually persist in the muscles themselves. In one study of mice, the results suggest that after nuclei in muscle cells multiply in response to an overload of training, those extra nuclei aren’t lost during subsequent periods of inactivity. They are retained (保留), essentially waiting to be reactivated. If you fell off the fitness wagon (马车) during the pandemic, don’t be frustrated. Once you have got additional nuclei, you are banking the capacity.
Ultimately, muscle memory is a payoff for all the past work you put into learning a sport.
| A．The best way to tap into it is to “get back on the horse”. |
| B．Physiologists, on the other hand, define it in a different way. |
| C．This convinces the researchers that muscle memory may not be long lasting. |
| D．That is to say, we can do the sports automatically without conscious thought. |
| E．It is generally safe to increase these elements by 5 percent every week or two. |
| F．It is evident that the more you exercise, the more muscle memory savings you will have. |
| G．All this news about muscle memory is encouraging for those who fell off the fitness scheme. |
2 . Online training is one of the fastest growing parts of the fitness industry. If you’re considering joining the online fitness community, consider these benefits and drawbacks.
One of the most popular reasons for working out following an online video is that it offers ultimate convenience. No need to roll out of bed at 5 a. m. to attend that 6 a. m. boot camp class, which may end up being full when you arrive.
Online training also has broad offerings. When you head online, you have instructors from around the globe, all ready and willing to help you master your favorite moves.
All these are undoubtedly positive-online training provides fitness resources to general consumers wherever they are, without requiring access to a gym or fitness studio.
Very few online fitness programs enable the instructor to see you, check your form, and offer corrections based on your performance.
| A．Another is the price. |
| B．But it’s not without problems. |
| C．The same goes for different types of exercise. |
| D．However, online personal training isn’t for everyone. |
| E．Instead, you can turn it on at home at your convenience. |
| F．That being said, online workouts aren’t perfect when it comes to safety. |
| G．This means you could perform exercises wrongly, or even unsafely, without knowing it. |
