Extreme ironing, anyone? However you're staying fit, you can count on SUBWAY® for a Fresh Fit sandwich — protein packed and loaded with flavor.

1. Wall Trampoline

This ain't your neighbor's trampoline. This is wall trampoline: a sport that combines the thrill of bouncing with, um, well — a wall. Honestly, it's something you just need to watch to understand because words alone don't do justice to how fun it looks.

2. Bossaball

If you've ever wanted to spike a ball with one swift kick, bossaball is your jam. It's basically volleyball on an inflatable bouncy court. The sport's won fans in Europe and South America, but not yet the U.S. You could be the first American bossaballer!

3. Flyboarding

OK, so jetpacks may be a ways off, but in the meantime, the Flyboard comes pretty close. Powered by the same turbines in jet skis, the Flyboard can catapult its riders as high as 32 feet and propel them underwater like a dolphin. We kinda want one.

4. Volcano Surfing

Ash boarding, volcano surfing — whatever you call it, you're sliding down a "1,600-foot volcanic slope" on plywood. So if that isn't extreme, like, then what is? Also, the Nicaraguan volcano where people do this is active. It's like the hot lava game IRL!

5. Jet Surfing

Surfing is hard. For one thing, you need to paddle. And second, you need to learn how to surf. Perhaps that's why JetSurf, a motorized surfboard, surfaced in 2008. With a top speed of 35 mph, you can "catch a wave," like, for real now!

6. Skyaking

You know that part in Indiana Jones and the Temple of Doom where the cast jumps out of a plane with nothing but a life raft? That's a sport now, except with kayaks. And unlike the movie, the idea here is to land on water, albeit at 50 mph.

7. Parasledding

Other things that aren't normally airborne: snowmobiles. But that didn't stop Canadian Eric Oddy from fixing a paraglider to one. He says he's flown his 440-pound snowmobile nearly 100 feet in the air, and he has the video to sorta prove it.

8. Rope Jumping

Has bungee jumping lost its thrill? Consider rope jumping, where the bungee cord is replaced with bolts, pulleys, and nylon rope — so instead of springing back up, you simply slow down as you free fall. Interested? Take the plunge with Dream Walker!

9. Extreme Ironing

Combining "the thrill of an extreme outdoor activity with the satisfaction of a well-pressed shirt," extreme ironing is real, and its athletes — "ironists" — have broken records and competed in world championships, the first of which occurred in 2002.

10. Mountain Unicycling

Every year, scores of unicyclists train for the North American Unicycling Convention and Championships, particularly the Cyclocross — a grueling, uphill obstacle course. Oh, and "muni" is short for mountain unicycling, for all you bi-pedalers out there.

The Tough Dodger presented by SUBWAY®

The Tough Dodger is a triathlon unlike any other, mostly because the athletes are pelted with dodgeballs. While this event may be too extreme to actually happen, whatever you're training for, you can start at SUBWAY® with a Fresh Fit sandwich.
