Hey DLD, you said that heating pads works good and be used as an another alternative for warming right? Which type of heating pads do you recommend and that is best to use , because there's the electrical ones that you have to plug , that may cause burns and damage , then there's the thermal and there's the microwaveable one that you heat up in the microwave for a couple of minutes and then you can get right down to your warm up to start exercising. Do you think that the one that is microwaveable is the safest one of them all. Do you think any of thesed types of heating pads can cause harmful effects to your body and health such as result in developing your cancer cells? Because it was said that the microwaves gives off radiation and the radiation is harmful to our body. Please get back to me as soon as possible on this?
