i got a presentation tommorow in my gym class in which i have to present two GOOD excersises to the class. These can be core body or with weights but core body is better. Any suggestions? Thanks

Burpees. IMO, the most brutal bodyweight exercise in existence. Guaranteed to make your gym coach will love you, and to make your classmates hate you for eternity. Your coach WILL use these, I promise.

We do these in an 8-count:

1. Standing / rest position.
2. Squat
3. Squat-thrust
4-5. Push-up
6. Squat
7-8. Jump as high as you can from a full squat

If there is a more brutal bodyweight exercise, DON'T TELL MY ****ING TRAINER.

EDIT: Pic of a Burpee. We do them with an added pushup when we thrust the legs out into pushup position.

And for the second, I dunno what kind of shape you're in, but the first position of planche is pretty nasty and great for your core and balance. It's a static hold, a very basic gymnastic exercise.

1. Palms on the floor. Elbows slightly bent.
2. Knees on your elbows.
3. Hold and breathe.

Alternately, walk around on your hands if you're a badass.
