The Posterior Powder Keg or Back Chain Blaster, a massive loadable vessel to blast your Posterior Chain.  

Posterior chain? What is that?

*The Butt, gluteus minimus, gluteus medius, gluteus maximus

* Hamstrings

*Lower back muscles(erector spinae)

other posterior chain muscles


*latissimus dorsi

A great way to engage this chain is swings.  Enter The Posterior Powder Keg, it weighs 25 lbs empty and can load up to approx 250 lbs with steel shot!!  A consistent routine of swings will keep your posterior chain healthy and strong.
