Post a video of your kettlebell swing anywhere online and someone will tell you to grab a heavier bell. Sometimes that is exactly the right call. Sometimes it is the worst thing you could do to that particular swing. The advice is identical in both cases, and so is the confidence of the person giving it.

Watch the 26 minute video I made covering this topic or read the article here https://kettlebell.monster/learn/science/should-you-go-heavier-kettlebell-swing

Before the spectrum: does the movement exist?

Put the bell down, or pick up the lightest one you own. Strip the load out and you find out what is actually there. Can you:

• hinge with the hips going back, flat back, shins near vertical
• set the scapulae, push the chest out, pull the shoulders down
• switch the lats on and keep the arms connected to the body
• stand up sharply out of the hinge with the arms doing nothing, no shrug, no shoulder drive
• delay the hinge instead of following the weight down
• finish standing where you started

If those are not there with no bell in your hands, no bell will put them there.

Passing this does not mean any weight will work. A bell that is too heavy will still take the movement apart, and one that is too light will still let you cheat with it. What passing means is that the weight question is now yours to ask. Everything below is that question.

Three answers, not one

Too light. The bell is below what your movement can already handle. It does not demand enough to make you use your legs, so you coast. The arms and shoulders raise it and the legs go quiet. The fix is to go heavier. Adding weight makes the shortcut stop paying, and the movement you have been skipping is forced to show up.

Right. The bell is heavy enough to demand real work and to reward clean mechanics, and light enough that you stay in charge of where it goes. The fix is nothing. Keep training.

Too heavy. The load overwhelms the movement. Faults appear or amplify, every correction you make is oversized, and every rep grooves something you will have to unlearn. The fix is to go lighter and rebuild the structure.

Three zones, three answers, and one of those answers is genuinely "go heavier."

Everything from here is about locating yourself on that spectrum, because the answer is worthless until you know where you are standing.
