Sledge Hammer Workouts
Let me be extremely clear: there is a hyooge difference between swinging a puny 8-10# sledgehammer and the massive 16-20# versions. A 16# is formidable...a 20# is horrendous! Keep the hands near the bottom end of the handle, preferably touching. Do not attempt to choke up. Choking up is the technique you'd use if working with the sledgehammer--we're using the hammer as an exercise modality, so the idea is to make it as difficult as possible!
I am liking the sledgehammer work here. 16lbs is a good hard workout on the tire. No sliding swing. Hammer time — Derek Poundstone
As you strike the ground, exhale with a "huhh!"-like sound. This will help to fully engage the abdominals, including the elusive transverse abdominus. With a heavy hammer, do NOT go for speed. Although you don't want to tarry, go for for quality of repetition by STRIKING the hammer with as much power and vigor as you can muster.
I prefer working the weaker side first, then the stronger. Make sure you always do an equal number of strikes on both sides. If your form deteriorates, be smart enough to stop swinging, so as not to injure yourself”! — Steve Maxwell
