Kickboxing is great for weight loss and fitness.
It is also good for building up your confidence which can some times get very low when you're on a weight loss journey.
More people should try kickboxing to lose weight and get fit, but it is something you need a base fitness level for or you should definitely start off slowly until you build your fitness level up - which shouldn't be very long!
If you are going to try kickboxing, go to a proper kickboxing gym. Don't think that just because a personal trainer or gym instructor has a couple of punching mits and a kick bag in his or her toolkit that they will be able to teach you kickboxing.
There are actually some very important techniques to learn and practice, especially if you ever need to use it for self-defense.
On a positive note, the techniques involved are few in number and relatively easy to learn compared to more intricate forms of martial arts so most people get up to speed really quickly.
Welcome again Masm, I look forward to reading about you losing those last few kilos and what works for you.
