The Bottom Line
If you follow these tips, you can save: $571/year*
If you invested this amount today and earned an 8 percent return, you would have $12,405 by retirement.**
*Savings if you buy the Nike + iPod Sport Kit instead of paying $50 per month to a gym. Comparable savings if you use a voucher book instead of a gym membership or join a university gym for a reduced fee.
**If you are 25 today and retire at age 65. We calculated that number here.
