Some enterprising young guy needed some advice on this, here you go.

1. After your wife has a baby she will want an exercise machine.

2. She will want the expensive one all her friends told her about. You will be tempted to say we can't afford it.

3. If you don't buy it her weight issue will be your fault. So be smart and buy it with no complaints--or else you will be facing marital celibacy.

4. You will be the only one to actually use the machine, if it is used at all. So try it a couple times to make spending on it feel better.

5. After a year, she will want another one. You will be tempted to say "hey you never used that other one..." Don't do it! Just buy the Nordic track, elliptical, stationary bike, treadmill, total gym, etc. (see #3).

6. The old one needs to go somewhere. You can get about 30 bucks for the copper in a treadmill at a recycling center to go toward the next thing her friends recommended.

7. Oh, don't buy it as a Christmas or birthday surprise. Instant dog house. And make sure you get a brand new one.

8. Your wife will not see this rationally, but will recall that you loved her for buying this stuff. Pays off down the road.

This is how to negotiate your marital exercise equipment issue without losing your marriage!
