Complete Dumbbell Training Without the Space Requirements
Every home gym owner faces the same challenge: dumbbells are essential for complete training, but a full rack requires significant floor space and represents a substantial investment. The Spartaks Strength 90LB Adjustable Dumbbells solve this dilemma elegantly, delivering the full training range from 15 lb to 90 lb in a single pair that occupies less space than two traditional dumbbells.
These aren't budget adjustable dumbbells with limited ranges or questionable durability. The Spartaks Strength design features a weight range of 15 to 90 pounds in 5 lb increments, giving you 16 distinct weight options per dumbbell—the same selection you'd find on a commercial gym dumbbell rack. The innovative reduced plate gap design ensures smooth re-racking between sets, eliminating the frustrating alignment issues common with lesser adjustable dumbbells. Combined with quick-change weight selection and premium construction, these dumbbells deliver professional-grade training capability in a fraction of the space.
Complete Weight Range – 16 Settings in One Dumbbell

-
Advanced: Heavy rows at 75 lb, progressing to 80 lb, then 85 lb—substantial weight that supports serious strength development
-

Frequently Asked Questions About Spartaks Adjustable Dumbbells
How long does it take to change weights?
Weight changes take just seconds. The quick-change mechanism allows you to select your desired weight and lift the dumbbell from the tray in one smooth motion. This speed makes the dumbbells perfect for supersets, circuit training, and efficient workouts where minimizing transition time matters.
Are 90 lb dumbbells heavy enough for experienced lifters?
For most exercises and most lifters, 90 lb per hand provides substantial training capacity. This weight supports heavy dumbbell bench presses (equivalent to a 180+ lb barbell bench), rows, shoulder presses, and all isolation movements. Only extremely advanced lifters pressing 100+ lb dumbbells would need additional weight.
How do these compare to buying fixed dumbbells?
One Spartaks Adjustable Dumbbells pair replaces 16 pairs of fixed dumbbells (15-90 lb range). In addition to significant cost savings compared to purchasing 16 separate pairs, you save 20+ square feet of floor space and eliminate the need for a dumbbell rack. The trade-off is slightly longer weight changes and the need to return dumbbells to their trays between weight adjustments.
What does the 2-year warranty cover?
The 2-year warranty covers defects in materials and workmanship under normal use conditions. If your dumbbells experience issues with the weight selection mechanism, structural integrity, or other quality-related problems within two years of purchase, we'll repair or replace them. This warranty demonstrates our confidence in the product's durability.
Do you offer delivery or shipping to Ontario and Quebec?
Yes! We offer free local pickup at our Toronto (GTA) showroom. For customers outside the GTA, we provide shipping throughout Ontario and Quebec, including Ottawa, Hamilton, Mississauga, Montreal, Quebec City, and all surrounding areas. Contact us for a competitive shipping quote.
Can beginners use these dumbbells?
Absolutely! The 15 lb minimum weight is perfect for beginners starting their strength training journey. The 5 lb increments allow for steady, manageable progression as strength improves. Many beginners appreciate having the full weight range available from day one—no need to purchase heavier dumbbells as you get stronger.
How much space do I need for these dumbbells?
The dumbbells and their storage trays require less than 2 square feet of floor space—roughly the footprint of a single shoebox. When in use, you'll need enough clearance for your exercises (typically a 6-foot by 6-foot area for most movements). After your workout, they store compactly in a corner, closet, or under furniture.
