Hex Bar Jumps are an amazing exercise to build explosive power.
They’re easier to learn than snatches and cleans and provide similar (tho not the same) benefits.
If you’re technique isn’t very good on snatches and cleans yet or you (or one of your clients) has no desire to take the time to learn them, then hex bar jumps are a great substitution.
To state the obvious, you should always land with your hips back (returning back to a perfect deadlift start position) and never try to catch the weight.
Do 8 sets of 2 reps at 30-50% of your deadlift max. Each rep should be fast and feel easy.
