Strength Training Kettlebells Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

ZELUS is the best-performing strength training kettlebells brand in July 2026, moving 20,000 units across 1 ASIN for 29.4% of Top 10 volume. Amazon Basics follows with 16,000 units (23.5%), ahead of Renoj on 10,000 units (14.7%).

With 7 brands splitting the Top 10 and 67.6% of volume sitting with three of them, this is a concentrated shelf — the leaders hold multiple listings or one very high-velocity ASIN, so a new entrant competes against established review moats rather than an open field. Average selling prices among the leaders run from $7.98 to $37.55, which frames the price band a competing listing has to justify.

Based on July 2026 data, this shortlist surfaces the two kinds of ASIN worth keeping an eye on — the ones that just broke into the Top 10, and the ones growing fastest month over month. Specifically, one ASIN forced its way in: B0731HYTZL booked 3K units at $43.25, with ▲ 200.0% MoM change. On the growth side, B00NLS0L0M leads positive momentum with ▲ 500.0% MoM growth on 300 units, with B08XSNQFFS close behind at ▲ 300.0% MoM on 400 units.

The two signals carry different weight. A fresh entrant means share has already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date. A steep growth rate works as the earlier warning: it marks demand that is still compounding, usually a month or two before the ranking catches up to it.
