Without a doubt, the best is if you have a standard heavy punching bag with plenty of space around. This way, you hit it from every angle and you can have the right fighting stance. Unfortunately, a punching bag stand limits opportunities. You can attack it only from the front, and you must be careful while kicking to avoid hitting the frame upright. But it's still much better than nothing for home training. An alternative option is to get a heavy-duty freestanding bag such as Wavemaster XXL or Ringside Elite that stands powerful kicks. Lightweight training equipment is out of the question; they are only suitable for people who want to improve their cardio endurance.
