Like Jon said, you need a very strong core and upper body.

And, hello shaun. =x

If I might add, a gymnast's training regime would be good too. They've got to be light yet strong, 'cause a heavy gymnast is being at a huge disadvantage. Also, there's minimal, or no need to buy equipment as most exercises use bodyweight.

What I meant was the strength and conditioning training part of gymnastics. Of course if you wanted to learn and perform actual gymnastic skills, the correct equipment is a must. Planches are FAR from easy to do. There is a lot of core and upper body strength required to perform them.

The reason I said there's not much of a need to purchase equipment for yourself, is that you can commonly find very very similar alternatives in parks of playgrounds. The two pieces of equipment which contributed the most to strength and conditioning training when I used to do gymnastics were the high-bar and rings. Most playgrounds will at least have some sort of a bar which you can hang from, thus allowing you the options of loads of different exercises. Some parks have designated areas with quite a bit of fitness equipment like bars, metal rings and parallel bars, or at least the ones I've been to.

Start with basic bodyweight exercises and exercises for developing explosive power, ie regular push ups, clapping push ups, etc etc. That's what's needed for gymnastics and breakdancing. Planks and if possible 'L-sit holds' for training your core. Regular squats and jumping squats for a bit of leg power. And now you've got a few simple yet effective exercises which you can do right at home.

If you're trying to work yourself up to a full planche, maybe you could take a look at this for reference, along with the static holds in the link you posted.

You mean the one in the Maktab Perguruan place? I'm not too sure. Lots and lots of space in there. Used to train there too, till my coach opened his own small gym.
