When it comes to improving your drum speed, especially bass drum speed, you’re going to have good days and bad days. Be patient as your leg muscles grow and stretch. Keep it mind that the legs and feet have more muscles and larger muscles than the hands and arms.
One thing that I always have to remind my own students is that your feet will never go as fast as your hands. It’s just how we’re built. Before you can develop bass drum speed, it’s good to work on bass drum exercises that help you develop control. A great resource for bass drum exercises is Colin Bailey’s book,
Bass Drum Control (affiliate link).
The Drumming System (affiliate link) says that one of the secrets to bass drum speed is to wear ankle weights while you practice. This well help you develop the muscles in your legs. After a practicing with them, go back and practice without the weights. You will notice results immediately. Another tip for developing bass drum speed is to try playing as loud as you can for a long period of time while wearing ankle weights.
A great exercise is to practice playing singles on your feet heel down and heel up. Playing heel down, you will feel the burn. If you find this boring, put a practice pad on the snare and play along. Years ago, my teacher Chet Doboe, the founder and musical director of the Hip Pickles Drum Band, taught me to practice the samba to develop my foot technique. The samba is great exercise because it allows you to work on controlling two notes in a row.
The Drumming System (affiliate link) recommends Hansenfutz (affiliate link) pedals for training. These are great because you practice in any chair that you are sitting in. You can even them under the desk in your office.
