My drummer's 50, and I am not too far behind him. However one thing we consciously remind ourselves when we play, is to create the majority of our music, to gives us a serious aerobic work out.
I love playing the guitar, but it can't revitalize my tired muscles like my FUNK BASS slapping, popping, and thumping.
When we play, there's this point where my drummer, and I would take our rhythm to a groove-zone.
The Groove-Zone is a concept where we turn-up the heat, and start to play faster, and faster while maintaining our playing accuracy like a fine tuned engine with pistons flying, while keeping pace with each sonic wave for more than 15 minutes.
Oh my goodness, its truly a spiritually transcending, and instinctive yet peaceful, very meditative state to play, and I feel really refreshed after a few sets of this; while feeding off the energy from my drummer.
When not playing, I find myself spending more hours at the gym, but there's no substitute for the work-out I get from our FUNK CHURCH.
Peace and Love,
Hal-
