Clark was a football (American Soccer) player in college and he dislocated his thumb.

He soon left OWU and joined NYU for their Acting Program.
Clark Gregg has been practicing Brizilian Jiu-Jitsu for 15 years. Clark gained his Black Belt after 11 years, in 2015. He trains with Renato Magno at Street Sports BJJ in Santa Monica CA.
"My pal Dave Mamet was directing a movie called "Spartan", and he had started doing Jiu Jitsu with a guy Renato [...]. He dragged me in there and said, "You know, you're playing a kind of a badass special secret service agent. You should, you know, this will help you". And I said: "Do I have any fights in this movie? I would love this if I do". He said "No, you don't. I just want you to go in there".
And so he took me in and I rolled a couple times and I liked it. [...] As any white belt knows, I was really getting suffocated and choked out a lot. At first I really didn’t dig that, but then I found myself going back a couple of months later and really getting hooked. And I kinda think that was about 12 years ago and I, you know, I had to, I would leave town and go do a job and not do it for a while [...] and I would always end up back there studying with Renato and with one of his black belts, a guy he called Richard Wilky.
You turn around you've been doing it a while and finally, I don't know, it must have been five years till I got a blue belt. And just a couple of months ago they gave me a brown belt. I really feel like I should be like a light brown belt, like a latte belt or something".

Basketball is his real love sports wise and he even practices at least once weekly on the Basketball Court. Clark has participated in multiple All Star Games, E-League Tournaments among other things.
"Before I did Jiu Jitsu, I was always looking for a workout which was fun. I don't love jogging, I get bored. Once out of every 10 times I'll enjoy it. I had to do another movie about 2 years before Spartan where I played basketball, and I loved basketball. But I played soccer in college and was a bad basketball player, but I used that of course to hire a really good basketball coach, a guy, now he is a shooting coach for the Oklahoma City Thunder. He taught me how to shoot and I started playing basketball religiously and I noticed that I would run till I was soaked in sweat if there was something fun going on.
Renato is still like – dude, you go to basketball three times a week, you can't come here more than once? And I can't help it, I love basketball. But before that I was boxing, just 'cause even boxing, as hard as it wasn't the guy, you know, I get hit a lot because I wasn't very good at that either – that was fun, there was something to try to improve at. So I spent two or three years doing kind of boxing sparring and trying to learn that technique before I did Jiu Jitsu. I love Jiu Jitsu, I even rolled this morning.
