The best thing about this product is that it helps one stay fit at home without stepping out of their house or office for any reason, i used to train in gym but could not find time due do my work commitments etc., so with dipathis workout routine I have found an alternative which can be done anywhere anytime by anyone! there’s nothing bad whatsover when using these products except if you are very heavy then they might feel uncomfortable after sometime however once your body adjusts yourself easily towards them its just fantastic.
