ok..I will try to be honest and help you here

# 1 tell her how hot she is...with perfect timing

#2 Make her so in lust for you that she wants you so bad she chases you around the bed and does atleast half the physical work in there with passion (great exercise)

#3 become a great chef that can prep meals that she likes and the quanity is not so much a issue if she desires more,since they are sooo healthy

#4 NEVER make her feel fat
this will just depress her and make her less motivated in my opinion

#5 tell her what a hottie she is ....again with perfect timing

# 6 repeat #2

unless you are a dime piece yourself with a great personality ...and you can get her wrapped around your finger so tight with lust for you that she worships the ground you walk on ....you will not motivate her to do anything in my opinion with your current tactics

and even if you were...heck that will wear off over the years
and you'll just be plain old you to her, after kids etc...which is when she will be the most vunerable to stress from criticism...under stress from a family.

I am giving you honest advice in my opinion and just trying to help you here dude

you will motivate her way faster to want to do stuff with you by making her feel hot than not.....make her feel like you think she is Gods gift to you and you are the one thats lucky to be with her

just look out later if it works...& you start having puppies none of this will really matter anyway...she'll have you by the b***s and you will be the project but probably in another way....in my opinion

but if you still want her to be hot ....you better keep making her feel hot first & foremost....if you make it that far

Swimming is great exercise ...fun and good to do together,get a tan....flirt around...make her feel like a hottie

I don't know what there is to do around where you live or might could give better advice on activitys

myself, I don't care for hiking or biking but love to swim
