Came across these a few months ago. Been working on the goblet squat with a 60 pound dumbbell and it can be a bit of a challenge, not as intense or stressful as barbell squats. Especially good if you dont have access to a gym, just substitute the dumbbell for a sandbag/bag of cement/small child and you’re good to go.
In an hour Dan John can use these things and get people to go from not hardly parallel to ATG.
The fitcast, Dan John squat video is usually on Youtube or google video.
haha i like the small child innovation for the goblet squat kc
