Sandbag Foundation
Thanks for checking out this video series, I really hope it helps!
After years working with new sandbag lifters, I have created what I believe is the ultimate heavy sandbag/bodyweight calisthenics training program, Sandbag Foundation. Check it out!
Note: The last couple videos in this Sandbag Basics video series are about a program I called the "One Sandbag" program. It's great and it works. I'm keeping the videos up for reference, but in my opinion Sandbag Foundation (the video linked above) is the better option. Good luck!
