At CIDA Fitness, I’m always looking for exercises that don’t just make you look fit—but actually make you move better. One of my all-time favorites for building athletic, real-world strength is the Medicine Ball (MB) Diagonal Chop.
This movement is powerful, dynamic, and incredibly functional. Whether you’re an athlete, a busy professional, or someone who simply wants to stay active and capable for decades to come, the MB Diagonal Chop deserves a place in your training program.
Why the MB Diagonal Chop Matters
Life doesn’t happen in straight lines.
We rotate to put groceries in the car.
We twist to reach for something in the back seat.
We turn explosively to hit a tennis ball or swing a bat.
The MB Diagonal Chop trains your body in the way it was designed to move—in multiple planes, especially rotational and diagonal patterns.
This exercise strengthens:
-
Core musculature (especially obliques and transverse abdominis)
-
Glutes
-
Shoulders
-
Upper back
-
Hip rotators
-
Total kinetic chain coordination
It also enhances:
-
Rotational power
-
Athletic explosiveness
-
Core stability
-
Neuromuscular coordination
-
Balance and deceleration control
And here’s the key: it trains your body to transfer force efficiently from the lower body through the torso and into the upper body. That’s what real performance is all about.
Starting Position
-
Stand with feet shoulder-width apart.
-
Hold a medicine ball with both hands.
-
Engage your core and keep your chest tall.
-
Position the ball high near one shoulder (as if preparing to swing an axe).
Your knees should be slightly bent and your weight evenly distributed. Think athletic stance—not stiff, not loose.
Movement Instructions
-
Initiate from the hips, not just the arms.
-
Rotate your torso and hips diagonally across your body.
-
Chop the ball downward toward the outside of your opposite knee (or slightly past it).
-
Allow your back foot to pivot naturally to protect your knees.
-
Keep your core braced and spine neutral.
-
Return under control to the starting position.
-
Repeat for the prescribed reps, then switch sides.
If performed explosively, this can be a power movement. If performed under control, it becomes a tremendous stability and anti-rotational strength builder.
The key cue I give clients:
“Move as one connected system.”
Safety Considerations
This is where smart coaching matters.
-
Avoid rounding the lower back.
-
Rotate through the hips and thoracic spine—not the lumbar spine.
-
Start with a light medicine ball until form is mastered.
-
Do not “muscle” the ball with your arms alone.
-
Keep the core engaged throughout the movement.
-
If you have a history of lower back issues, begin with controlled tempo before progressing to explosive reps.
When performed properly, this movement actually strengthens and protects the spine by improving force distribution across the body.
Why It’s Essential for Athletes

You need to produce and control rotational power.
The MB Diagonal Chop mimics sport-specific movement patterns. It teaches your body to accelerate and decelerate rotational force—both of which are critical for performance and injury prevention.
Athleticism isn’t just about strength. It’s about how well you apply strength.
Why It’s Essential for Everyday Life
Even if you’re not an athlete, you are still a human being designed to rotate, bend, and move dynamically.
As we age, we don’t lose strength first—we lose coordination and power. And that loss affects our ability to:
-
Carry luggage
-
Lift grandchildren
-
Do yard work
-
Play recreational sports
-
Move confidently and without fear
Functional training helps preserve the quality of movement that makes life enjoyable.
In his book Functional Training, Juan Carlos Santana explains that effective functional exercise must be “multi-planar, multi-joint, and performed in an upright position that integrates acceleration, deceleration, and stabilization.”
That description fits the MB Diagonal Chop perfectly.
Programming Suggestions
For stability focus:
-
2–3 sets
-
8–12 controlled reps per side
For power focus:
-
3–4 sets
-
5–8 explosive reps per side
-
Full recovery between sets
This movement works beautifully in warm-ups, strength circuits, or athletic performance sessions.
Final Thoughts
I love the MB Diagonal Chop because it respects how the body truly functions. It connects the hips, core, and shoulders into one integrated system. It builds power. It builds resilience. It builds capability.
And capability is what we’re really after.
Fitness isn’t just about aesthetics. It’s about staying ready—ready to compete, ready to move, ready to live fully.
Train movements that matter. Train patterns that transfer. Train for life.
