If you just started playing the drums, then as you know, you need to warm up. And for
Beginners, (and i even do this sometimes) is stick to a normal basic beat and build 
up. What i mean is this

H|o-o-o-o-o-o-o-o-
S|----x-------x---
B|x-------x-----x-
                           Now to build up, try this
H|o-o-o-o-o-o-o-o-
S|----x-----x-----
B|x-x---x-x---x-x-
                           And keep working up
H|o-o-o-o-o-o-o-o-
S|----x---------x-
B|x-x---x-xxx-----
                           Now just keep making things up sticking with the basic
                           beat (1+2+3+4+) I also suggest occasionally slowing or 
                           quickning up like this
H|o---o---o---o---
S|----x-------x---
B|x-x---x-x-----x-
                           Heres one from Song two by Blur that i like
H|o---o---o---o---|o---o---o---o---
S|----x-------x---|----x-------x-x-
B|x-------x-x-----|x-------x-x-----
                           You can also double the hi hat hitting so heres a good 
                           warmup altogether

H|o-o-o-o-o-o-o-o-|o-o-o-o-o-o-o-o-|o-o-o-o-o-o-o-o-|o-o-o-o-o-o-----
S|----x-------x---|----x-------x---|----x-------x---|----x-------f-f-
B|x-------x-------|x-x---x-x-----x-|x-------xxx-----|x-----x-x-------

H|O---O---O---O---|O---O---O---O---|O---O---O---O---|O---O---o-------
S|----x-------x---|----------x-rrrr|----x-x---x-x---|----------rrrrrr
B|x-x-----x-x-----|x-x-x-x-x-------|x-------x-------|x---x-----------

r mean drumroll and f means flam, if you didnt know. hit that crahs cymbal at the
beginning of each new line if you want. and if you want to ad something else as a 
backup beat other than a hi hat, hit a ride cymbal on the top with the tip of your
drumstick (not hard) at the same rate as the hi hat, if you just understood what i 
meant. But this is just an example, add anything you want in there. Good Luck!
