Master the sand bag
There are those sandbags you need to carry uphill too. The best way to carry one depends on the size of the person. “If you are a smaller person and the sandbag drapes over the front and back of your shoulder and you carry it on one, then try putting it on the upper part of your back and grip it with both hands,” he advises. “Take a sandbag onto a staircase or a steep hill and walk up and down it numerous times to train yourself.”
