You naturally will have a stronger side so working both separately (but equally) will help develop total strength. I.e. Two equally strong sides. In turn, this will lessen the chances of injury because you don’t have one side working harder leading to overstressing or one side failing due to weakness.
Try this circuit once a week and notice how much quicker those PBs come along!
Do your weakest side first, then strongest, then move on to the next exercise – 3 x 12.
