The main thing I recommend when choosing an optimal weight training program is to spend a little more money. The price difference between the products is minimal. Some of the products are cheaper, but the difference is not much. The most expensive product is definitely the Zumba workouts, but even if you only spend 5$ on Zumba, it will have better results than the freebies. So, if you can afford Zumba, do it. However, I would also recommend Zumba workouts for those who are still interested in a more effective training. But it would be better to use the freebie if you can't afford Zumba. The next step would be to do your own fitness training. There are a lot of trainers who train you how to walk. You can do some basic exercises here, such as walking left and right. You can also use a trainer for more advanced exercises, like yoga, pilates or walking on the treadmill. It will take about 3 hours to achieve your goal. But you could also do it faster.
For those who want to go to the gym and train at their own pace, they will need to buy the products with the help of a professional trainer.
