• • It is also important that you know how to correctly spot someone to assure his or her safety. When spotting someone, always be prepared to give a little assistance when they reach muscle fatigue (cannot complete the rep on their own). You don't want to help so much that the rep becomes easy for them to complete--give just enough assistance so that they can complete the set, but it is still challenging for them. Also, only provide assistance on the positive phase (the part that requires the pushing or pulling motion). Still have your hands ready to help, but don't help with the negative phase (the part where you resist the weights force)--the lifter should try to slowly resist the force of the weight all on his/her own.
