Working out and stuff never gave me more energy. If anything it leaves you feeling tired and achy the next day, but it makes it easier to get up and start your day. You don't get into that slump of doing nothing and sitting around the house bored as hell all day long. It's sort of mental. You're more likely to play a sport or something active on a daily basis, especially when you've just done it not too long ago. Your body and mind is in that beast mode, and you want to continue feeling healthy and maintaining a healthy body.
I see. If I know anything, I know it works! I used creatine with lifting during my prime growth years, and my chest blew up. I'm so much more bulkier than anyone in my family. Surprisingly, despite not lifting consistently for the past 5 years, I'm still bulky. I lost a lot of my bicep and trap muscle though.
I love parkour. We used to try to do that stuff all the time as a kid. Too old now. Too many responsibilities. Breaking my leg again isn't going to happen.
Until now, I've always underestimated the power of plyometric/calisthenic-type exercises. If you do them right and maybe even modify them slightly to add more difficulty, they can really do a number on you. Makes you think that lifting weights is actually a less intense workout. There are plenty of professional athletes (e.g. Herschel Walker) who got jacked without weights. Still though, I like weights because it allows you to focus on a single muscle and really push it to its limits. Calisthenics usually involves several muscle groups, and almost always your trunk muscles.
