If your father figure is into fitness...or just starting out, a great watch to help keep him on track would be ideal. Try a Polar watch!! This one is really cool...
If your guy is less into fitness and more into beer...a beer of the month subscription might be a cool idea...Check out Beer of the Month Club and see what I mean.
If he's been working hard all year at being a great dad, then maybe a massage is what he needs. Yes, men need those too! Check out Groupon or Living Social for great deals on a massage in your area! Dad will thank you!!!
Don't forget to with that amazing man a Happy Father's Day for me!!
