what do you mean findind a setup is a rarity? u just need a bar and some floor space and a load of weights. use 35lb plates so u can go low and get a nice ham stretch, keep your knees very slight bent and your back completely flat, feels the hams stretch then explode back up and squeeze hams and glutes, then lower slowly and repeat. Side effect is improved grip stength and forearm size. Its a sick lift bro give it a try
