Pelvic floor exercises get recommended constantly and understood rarely. Most people know the word "Kegel" without knowing what the muscle actually does, why weighted balls train it differently than a voluntary squeeze, or why starting with the wrong weight can undo the whole point of the exercise.
What the Pelvic Floor Actually Does
The pelvic floor is a group of muscles that supports the bladder, uterus and bowel, and controls continence. Pregnancy, childbirth, ageing and the hormonal shifts of perimenopause all place strain on it, and unlike more visible muscle groups, it's easy to go years without noticing it's weakened until symptoms — mild incontinence, reduced tone, discomfort — show up.
How Weighted Balls Actually Train the Muscle
A standard Kegel squeeze relies entirely on remembering to contract the right muscle correctly, which a surprising number of people get wrong without feedback. Weighted balls solve that by giving the muscle something physical to respond to: the body reflexively grips to keep the weight from slipping, engaging the pelvic floor more naturally and more consistently than a squeeze performed in the abstract. It's the same logic behind progressive resistance training elsewhere in the body — heavier weights, applied gradually, build strength over time.
Why Progression Matters More Than the Starting Weight
Starting too heavy defeats the purpose. Both LELO's Luna Beads Classic and INTENSE's Charli kit are built around graduated progression rather than a single fixed weight — Luna Beads pairs 28g and 37g balls on a soft silicone connector so you combine them as strength builds, while Charli's three-level set moves from a genuinely gentle starting point up to a more advanced level. The point of either system isn't to reach the heaviest option quickly; it's to only move up once the current level feels comfortable and controlled.
Two Different Approaches to the Same Goal
The two kits solve the progression problem differently. Luna Beads Classic uses a single 35mm size — sized specifically for women over 30 or who have given birth, when a slightly larger fit tends to be more comfortable and effective as a starting point — with four weighted balls you mix and match on a connector as you progress. Charli takes a level-based approach instead: three separate balls, each a different size and weight, worn one at a time and swapped out as a level starts to feel too easy. Charli is also fully waterproof, which Luna Beads' harness design isn't built for in the same way.
When to Start and What to Expect
Postpartum recovery and perimenopause are the two life stages most commonly associated with starting pelvic floor training, though there's no reason to wait for either — building the habit earlier tends to make maintaining it easier later. Consistency matters more than intensity: a few minutes of wear a few times a week, worked up gradually, does more than an occasional heavy session. Reported benefits include better muscle tone and bladder control, and many women also notice increased sensitivity during sex as pelvic floor engagement improves. If you're dealing with pelvic pain, prolapse symptoms, or anything beyond general weakness, it's worth checking with a pelvic floor physiotherapist before starting rather than guessing at the right approach.
