You\'re not getting the intensity you want: If the muscle stimulation isn\'t as strong as you\'re used to or you can\'t work at your usual intensity level, the pads may need replacing. The pad surface is uneven and flakes off: If that happens the EMS pulses cannot be distributed as effectively. This means that you won\'t be getting the most out of your training. If it\'s pierced of torn, replace immediately. The pads are designed to last approximately 20-30 sessions of 30 minutes, or 4-6 weeks depending on usage.
