For lighter home workouts and beginners, the 4-in-1 set is the most accessible option. If you want more resistance and room to progress, choose the 5-in-1 set.

The 4-in-1 set offers four weight settings with a maximum of 2.3kg per dumbbell, while the 5-in-1 set offers five settings and up to 5kg per dumbbell. Both use a compact quick-release design.

Choose 20kg per dumbbell for a more compact progressive strength setup. Choose 36kg per dumbbell if you want a higher maximum load and more room for long-term strength progression.

Quick-Change dumbbells are designed for faster plate changes in a compact format. The Cast Iron set uses traditional spinlock plates and can also be configured as a barbell.

The 4-in-1 and 5-in-1 options are sold as pairs. Quick-Change options are listed by maximum weight per dumbbell and are available as Single or Pair configurations. Cast Iron weights refer to the total weight of the complete set.

The 4-in-1 and 5-in-1 dumbbells are the quickest to adjust, making them ideal for circuits and workouts with frequent weight changes. The Quick-Change model also allows fast plate changes while supporting heavier loads, while Cast Iron dumbbells use traditional spinlock collars and take slightly longer to adjust.
