CAP Barbell Neoprene Dumbbell vs Lifeline Fitness Hex Neoprene Dumbbell

Buy the CAP pair if you want two matching 4 lb dumbbells for a full set of light exercises. Buy the Lifeline single if you need one dumbbell or want to build a set one weight at a time. Both use a hex-shaped iron core dipped in neoprene, so build and grip are close. The CAP handle is a plain medium-diameter cylinder; the Lifeline handle is contoured and slightly thicker in the center, which owners of that style say reduces hand fatigue on longer sets.

• Choose the CAP Barbell Neoprene Dumbbell if you want a matched pair of 4 lb weights in one box for two-handed or alternating work.
• Choose the Lifeline Fitness Hex Neoprene Dumbbell if you need a single 4 lb weight or plan to add one weight at a time across the 1 to 10 lb range.
