Happy New Year from TED-Ed! If you resolved to exercise more this year, then you’ll love this playlist of original animated videos, curated just for you. Behold, 5 TED-Ed Lessons to watch while you’re at the gym:

1. Why sitting is bad for you

Sitting down for brief periods can help us recover from stress or recuperate from exercise. But nowadays, our lifestyles make us sit much more than we move around. Are our bodies built for such a sedentary existence? Murat Dalkilinç investigates the hidden risks of sitting down. Watch this TED-Ed Lesson below.

2. What makes muscles grow?

We have over 600 muscles in our bodies that help bind us together, hold us up, and help us move. Your muscles also need your constant attention, because the way you treat them on a daily basis determines whether they will wither or grow. Jeffrey Siegel illustrates how a good mix of sleep, nutrition and exercise keep your muscles as big and strong as possible. Watch this TED-Ed Lesson below.

3. What would happen if you didn’t drink water?

Water is essentially everywhere in our world, and the average human is composed of between 55 and 60% water. So what role does water play in our bodies, and how much do we actually need to drink to stay healthy? Mia Nacamulli details the health benefits of hydration. Watch this TED-Ed Lesson below.

4. The treadmill’s dark and twisted past

The constant thud underneath your feet. The constrained space. The monotony of going nowhere fast. Running on a treadmill can certainly feel like torture, but did you know it was originally used for that very purpose? Conor Heffernan details the dark and twisted history of the treadmill. Watch this TED-Ed Lesson below.

5. How playing sports benefits your body … and your brain

The victory of the underdog. The last minute penalty shot that wins the tournament. The training montage. Many people love to glorify victory on the field, cheer for teams, and play sports. But should we be obsessed with sports? Are sports as good for us as we make them out to be, or are they just a fun and entertaining pastime? Leah Lagos and Jaspal Ricky Singh show what science has to say on the matter. Watch this TED-Ed Lesson below.
