Even the best athletes have trouble nailing down simple ballet choreography.  When New England Patriots tight-end Rob Gronkowski stopped by a studio to take ballet lessons from principal soloist Nathalia Arja, he probably wasn't expecting it to be that hard.  Except, watching his 6'6" frame attempt to leap through the air proves ballet is one of the hardest sports ever.  It requires endurance, flexibility, and grace.  Though the football player was a good sport and had plenty of confidence, his moves did make us burst out laughing.  Rob doing ballet is all of us because no one perfects their arabesque moves in one shot (unless you're Misty Copeland).  Watch his best attempts above, and then check out that time Misty tried to help Jimmy Fallon brush up on his ballet skills.

Whether you're drowning yourself in smoothies because it's too hot to eat oatmeal or escaping to a studio class for a blast of A/C, Summer can be a tough time when you're active.  While we love running on the beach and going for a swim, there are definitely some problems that can arise ... and every yoga class is a hot yoga class, whether you like it or not.

When You Work Out in Shorts Because It's Hot and EVERYTHING CHAFES

When You Try to Go to Hot Yoga, and Realize it Was a HUGE Mistake

Everything is sweat.  E. Ve. Ry. Thing.  Your body is basically a shower head.

When You Take a Studio Class With A/C, and Feel Like This ...

... And This

When You're Training For That Half Marathon You Signed Up For in the Fall ...

... and didn't realize that meant training in the Summer.

But the Only Time It's Cool Enough to Run Is at Night, So You Cover Yourself in Reflective Stuff

The '90s are in, it's okay.

When It's So Hot, You're Literally Living Off Juice and Smoothies

Just set my money on fire.

When It's Less Than 70 Degrees Out and You Can Work Out Outside Without Dying

#blessed

But the Rest of Summer Is Like ...

Basically swimming through your own sweat.

And of Course, When You Get Runger and Derail All Your Summer Eating Goals

Oh well!

It's not called a workout for nothing!  That sh*t is hard!  And these Instagram pics prove it.

Who wants to talk about tampons and vaginas and chemicals?  No one because it's not exactly exciting or sexy stuff.  But it's important to be aware of the crap that might be in your tampons, and Maya Rudolph wants you to know.  She made up a little jingle — a vajingle — about it, and it goes a little something like this.

If all that healthy eating and crunches aren't bringing you flat, carved abs, maybe laughing at these Instagram quotes will.
