When practicing striking techniques, they can be practiced either in the air where you don't hit anything or you can hit a bag or some other solid target. Does anybody prefer one method over the other? As for me, I do both and I think both methods have their own benefits. I've met some practitioners who like to hit solid targets so they don't do much, if any air training but I do believe air training has its value so that's why I do it in addition to bag training.
