Shazzas Bootcamps is excellent. I started bootcamp training with them 4 years ago and since joining have had a baby and now do the "baby bootcamps". I highly recommend this to new mums. It is a great way of shedding that baby weight whilst exercising outdoors with other mums. Trust me you will notice a difference to your fitness after only a few sessions. The value for money is amazing.
Having started two years ago I have found the classes very rewarding in terms of the results i've seen in myself and have had many others comment about not only my weight loss but my improved muscle tone, confidence and happiness. In the time i've been doing the classes i've noticed high return rate of people that have attended previous classes. I have also noticed the fast growth of the number of people who train with Shazzas which is a testament to the a particular winning (& probably secret) formula which i believe is overlooked by gym and boot camp chains. The results however are at least the same if not better!
If you're not a gym person, but want to improve your fitness, then I highly recommend Shazza's Boot Camps. The trainers are fantastic. They cater to all levels and really motivate you - but not in an army style boot camp way. It's very friendly and lots of fun. You'll see a definite improvement and at about $10 a class it's great value.
