Try to use your wrists or your fingers and not use your full forearm, or you will not get much faster.

Even these basic variants of the blast beat can be used in many different ways depending on the tempo played, whether you're using hi-hat, ride bell or other cymbals, whether you're leading with cymbal or snare, whether you play in triplet notes, etc. Play around with these variants and discover what an actually versatile form of drumming blast beats can be.

Don't forget - not everyone uses double-bass and you don't have to either. If you play in small pubs and clubs and/or If its not muted, double bass drum has a tendency to obliterate anything else that the other band members might play (particularly when played fast).

A few variations include the Cannibal blast (after Cannibal Corpse who purveyed the style) which involves playing a 16th note double-kick roll while hitting only 8th notes on the snare, the Suffocation or Smith blast (after Mike Smith of Suffocation for inventing it) which involves hitting the snare and kick and often hi-hat or ride bell in total unison and the gravity blast which involves playing a basic Euro-blast pattern on the kick and cymbal but using a one-handed roll technique using the snare's rim to create what sounds like a two-handed drum roll with only one hand.

Make sure you stretch a bit before doing it for long periods of time because your hands might cramp up. Keep your arm away from your body and make sure to hit the snare close to the center of the head. Tensing up for a blast beat for too long will give you one hell of a bad muscle cramp!
