This is certainly not a standby in my workouts, but my one buddy always finds a way to turn an odd object tool into a bodybuilding tool.
I'll catch him using kettlebells for side laterals, you know, crazy sh*t like that which never makes sense.
Anyway, I threw these in one day with heavier weights, added some body momentum and there ya go, I no longer have an isolation movement and can train heavy.
You can turn this movement into a full range swing where the bag goes all the way overhead and you squat down slightly allowing the bag to pass through the legs.
Now, we have a sandbag swing!
