I have been researching past week for a suitable heavy bag but no success. Been looking all over online, on craigslist/ebay, and even in store. I am looking for a bag weighing around 120 to even 150 lbs. Currently weigh in at 190lbs and plan on filling my weight upto 220 before spring. So I am looking for something that can last throughout my personal training, which is why I am avoiding 100lbs bags so I won't be pounding on them throughout my weight gains. Does anyone have any links to help me find such bags? Yes, I am worried about cost efficiency so please, nothing more than $300. I have found unfilled bags, but would prefer filled bags, due to me trying to avoid manually filling the bag. Also, since Black Friday is on its way. Does anyone have any deals? If we are speaking of Black Friday deals, then I can actually settle for a 100lbs bag. Thank you for the help guys.
