Straight and simple, I absolutely love the box jumps.

In sports, having powerful triple extension (hip, knee, ankle) and explosiveness makes you a hard ass athlete. These three main joints must extend together to produce a vertical force (jumping, sprinting) or diagonal force (hitting, tackling). Box jumps allows us to train all three elements extremely quickly without a difficult learning curve.
Many coaches like to use the power cleans and snatches to emphasize on the triple extension, which is fantastic. I’m a former weightlifter myself, and I know how powerful it makes a person. However, seeing how many athletes do the lifts, it looks more like a “Hip bump and barbell swing” than a snatch or power clean. There’s no vertical explosion. It’s a horizontal explosion. Useful if your sport requires you to bang your hip into a wall or punch or to throw someone off your hip like in jujitsu. NOT useful in sprinting, tackling and jumping.
The box jumps are much simpler to teach, and equally effective. Loading parameters can be in the form of;
- Box height
- Weighted vests
- Start methods (Standard, paused, sitting, single leg launch, single leg land)
These variables make box jumps a tool that’s very easily modifiable and also extremely fun. Combine this explosive movement with a solid strength movement such as the deadlifts, squats and unilateral movements such as lunges and sled pulls, you’re in to developing an extremely powerful athlete.

Other benefits of the box jumps include;
- Improving bone density and joint health (Impact used wisely, strengthens it)
- Improving flexibility (One needs to raise the knees high to get on the box)
- Improves coordination
It’s also a great cardiac health builder if combined with other exercises in a circuit. BUT!
I really wouldn’t recommend is using the box jumps for higher repetitions like, 10-20 repetitions. Jumping is to improve explosiveness. After 6 repetitions or so, you’re going to jump a little lower and squat lower to slice right into the box. That sort of defeats the purpose of a box jump as you’re not actually maxing your explosive potential. In a circuit, I’d use box jumps as the first exercise, and move into more muscular endurance movements for the last few exercises.
Example:
- Box Jumps (5)
- Kettlebell Swings (20)
- Bear Crawls (10 meters)
- Squats (20)
- Farmers Walk (20 meters)
Till the next post, go do some box jumps! Now!
