For punching routines I'd go with the 80 pounder at 79$. And with this bag you can opt for kicking workouts as well. ***EDIT nevermind! go with #3 I didn't notice all of the stuff it included!***
It's really up to you, personally I'd go with #3 because speed bags are awesome for hand-eye coordination improvements and cardio....plus they are fun as hell!
I used to have one....and I put it through hell and it never tore apart.
Here are a couple of ideas:
#1 thing to do for these workouts though is to make sure you got good form...with this kind if impact you don't want to hurt yourself. Maybe ask a local martial artist for proper form or sample exercises to get you ready.
Now onto the exercises....
Buy cheap dumbells weighing from 1lb to 5lbs.
Hold one in each hand
Start with the 1lb dumbells and punch non-stop until you are near failure.
Rest 30 seconds. (Adjust accordingly)
Start with the 2lb dumbells and punch non-stop until you are near failure.
rinse and repeat up to 5lb and down back to 1lb.
Believe me....you will become an incredible punching machine if you do this routine a couple times a week.
Next one is shadow boxing...pretend your punching bag is someone trying to take you down...pretend to dodge....counter attack...strike him...land some kicks...do this until near failure. Rest 2 minutes....rinse and repeat 2 times. Use your knees and legs and move around the bag...this is good for leg conditioning.
Next one is all out straight leads...for your punching form you should be hitting
the punching bag at the same area where your nose would be if you we're the punching bag...punch with your right and as you retract punch with your left...kind of like a piston action motion. Stand still and have you feet should width apart...maybe have the one you are more comfortable with planted a little in front of you. You can either go all out until failure or you can do 10 sets of 20 punches (10 each hand) with barely 2 seconds of rest between sets.
PM me if you want more ideas!
Hope I helped!
