“When are you guys coming out with handles for the Mammoth Belt Squat?” …they’ve been here. They’re just not made by us 😅 The TNT Hellbox Attachment made by @porter_physed goes on most lever-based belt squats, giving you handles that amplify the belt squat experience. With 11 angle positions and 5 handle heights to choose from, your leg days are going to ask you why you didn’t pick this up sooner.
