Umbreon and Kage i trained with my friend who is an MMA fighter for one summer so we could do the spartan race. the Cardio he does is so intense i thought i would die sometimes.
We did this thing that was super hard where u did 10 pushups then 10 military shoulder presses with no weight then 9 pushups and 10 military shoulder presses then 8 pushups all the way till we did 1 pushup and 10 presses. By the time you reach 4 pushups, you might as well be doing a thousand. Then to take a break between excersizes, you jump rope 100 times then 100 on each leg. But you'll feel like a man afterwards its fun. lol.
On the note of jab dd grab. I sometimes do this because jab is a good way to kind of confuse your opponent and get them to spot dodge. Really what i'm dong in that situaton is waiting for them to do something during the time that you're DD, and grab is only one of a multitude of possible responses. For example if they are fox and they fsmash and you go into grab you're probably gong to get stuffed but if u just dd a little longer you can drill shine or whatever you feel like at that point.
I bet you're right that DD is safer because it lets you reply in any possible way than instead of just jabbing.
