There’s much debate around with subject, and in reality, it very much depends upon your own physicality and to a certain extent your general lifestyle too, the amount of sleep you get, how good your diet and nutrition is and how long it takes your body to recover. If you lack in essential vitamins and minerals, sleep deprived, stressed and overworked, then your recovery time will be impacted, and you do need to give your muscles chance to grow and to recover. The rack workout on a squat station will continue to build muscle for up to a staggering 36 hours even after you’ve worked out so if you overdo it and return to lifting heavy again too quickly, you will be putting undue pressure on your body. Generally speaking though, if you are relatively fit and healthy and following a sensible nutritional program, three times per week is a good recommendation.\r
