Picnic Table Workout!!! It will take over the industry by my prediction.
A sample…
Thats actually a good friend of mine his name is Zach Even Esh. He is a strength coach for mainly high school (combat athletes) in New Jersey. You can find his articles on t-nation and elitefts. Smart, creative dude who likes to use unconventional training and shows you you don’t need a fancy facility to get the job done.
He trains athletes in his garage and in the park.
Big into sleds, kettlebells, powerlifting training, strongman, and dinosaur. Apparently picnic tables now too. lol. I will try to get him to join to the forum.
I assume the progression for beginners would be:
1 - Lawn Chair Workout
2 - Bistro Table Workout
3 - Park Bench Workout
4 - Picnic Table Workout
5 - Bus Stop Shelter Workout
Periodization and loading would depend on if anyone was sitting on these items while you were using them.
Before weights I do jumps onto the seat of a picnic table at the park where I lift.
If he had no time shouldn’t he be eating his sandwiches at the same time?
Hey! I thought that was my idea! We used to do hypers and reverse hypers from a picnic table cause it’s so heavy it won’t flip on you.
Too funny. I’m going to start training!

We used to used to push a picnic table across a football field as fast as possible. Same kind of workout as sled dragging…it will kick your butt!
Just make sure you get a picnic table like the one in the picture that has the metal legs that look like sled runners. 
Next will be the picnic basket diet by Yogi Bear
Better do the workout early, cause when Yogi arrives, you better leave!!
Thats the idea eat yogis food then runaway and the one who survives wins.
It doesnt matter how fast you are when running away from a bear as long as you outrun somebody.
This is a much funnier thread than the one on torture! 
i wont be able to sleep tonight, too busy laughing at Yogi bear eating up slow park bench lifters! Maybe we better send Poo bear out 1st with his hunny tub?
If you don’t run fast enough and it grabs your shorts you’ll end up with a bare behind. sorry guys :o
