Regardless of if itās kicking or punching or both, you should have a plan going in. Just throwing anything and everything as hard as you can for as long as you can isnāt very smart nor efficient. Thatās not to say a āburn outā round or two isnāt good, but you know what I mean.
Jobo made a great point - listen to your body. Keep proper technique. Also as he he said, define what youāre looking to gain and work towards that.
When I focus on kicking, I do a bunch of things. I never counted a total though...
Fighting stance, and Iām pretty much taking a small step/shuffle on every kick.
All kicks done with front leg x 20, then rear leg x 20...
Front kick
Roundhouse
Side kick
Hook kick
Inside-out crescent kick
Outside-in crescent kick
After that, Iāll switch to opposite foot forward and repeat. I sometimes throw in an additional kick, replace a kick, or add/replace a kick with a combo like front kick then on the same leg roundhouse without touching down. Depends on my mood.
When Iām doing that many kicks, itāll be a balance of speed and power, but mechanics come first. Sometimes Iāll do 10 of each kick instead, but Iāll focus far more on speed or power. Depends on my mood.
Regardless of how many and what Iām doing, I keep a good pace. I try to get my heart rate up and keep it up. Not all out heart rate, but pushing myself pretty good.
After all the kicks, Iāll do some kick-punch combos. Something like front kick-straight left-right hook. Sometimes Iāll go slow and pay attention to where my feet are landing, where my hands are, my angle of entry and exit, etc. Sometimes Iāll just go fast. Sometimes Iāll go hard.
On punching focus days, Iāll do something similar, only moving in jab x 20, jab-cross x 20, jab-cross-hook x 20, etc. Just like kicks, some days Iāll go slow and pay attention to my movement and mechanics, so days Iāll go at a cardio pace, some days Iāll go all out power.
Then other days, Iāll simply do rounds. 12 x 2 minutes, 1 minute rest between rounds. Iāll constantly do combos, moving in and out. Iāll have a fight in my head
The biggest things are change it up, alternate heavy/difficult days with lighter/more technical days, and get adequate rest. Stretching before and after too. And I really like the foam roller for my upper back after Iām done. The hot tub was great when I had access to one afterwards to recover.
To take it up another level, I wear a Fitbit and track my heart rate. Iāll work harder when need be, and back off a little when appropriate.
Sorry for the long manual here. I did this about 4 x a week when I was getting ready for a tournament. It helped A LOT. While it seems like all that would take forever, from warmup to cool down it would take about 50 minutes total.
