With just 12 weeks remaining before defending his Mr. Olympia<\/a> title, Derek Lunsford<\/strong><\/a> isn\u2019t simply lifting heavier weights. Instead, he\u2019s experimenting with <\/strong>electrical muscle stimulation<\/strong><\/a> (EMS) to boost arm growth<\/strong> with even greater muscle contractions<\/a> during training \u2013 a strategy that has already sparked debate among bodybuilding fans.<\/p>\n Lunsford recently shared a full arm workout on YouTube<\/a>, where he used EMS pads throughout much of his triceps<\/a> and biceps<\/a> session. While some online have questioned whether the technology is unnecessary or even \u201clazy,\u201d the reigning Olympia champion<\/a> made it clear he believes it\u2019s simply another tool to maximize muscle stimulation.<\/p>\n
