Frequently Asked Questions
Which dumbbell should I buy next?
Compare the cost-efficiency ratio (cost per muscle/step improvement) of each dumbbell. The best upgrade gives the biggest muscle boost relative to its cost. Use this calculator to find the optimal upgrade path.
How is cost-efficiency calculated for dumbbells?
Cost-efficiency is the cost divided by the muscle per step improvement over the previous tier. A lower ratio means you get more value per win spent.
Are expensive dumbbells always better?
Not always early on. A high-tier dumbbell may have great raw stats but terrible cost-efficiency if the price jump is massive. Buy the dumbbell that gives the best ROI for your current win budget.
