Would like to lose weight for my son's wedding

toyota

My son is getting married in Oct. and i would like to lose at least 40 lbs. by then for the wedding. I have lost alot of weight before & gained it all back. I used to be fit & exercise regular, but i have not been doing any exercising in the past 4 yrs.
I have all kinds of exercise equipment at home & just don't use it. I need to dust the dust off my equipment & use it.
Equipment i have is :
Elliptical machine
Gazelle machine
Bun & Thigh Rocker machine
Magic Leg machine
Weight bench with barbell & weights
Dumbbells all sizes
exercise ball
all kinds of dvd's
step for step aerobics
stair climber machine

I got all this stuff & have no excuse for not working out. I need to cut back on eating and eat right and exercise so i can lose some weight for my son's wedding. I weight 229 lbs. and would like to lose at least 40 lbs. by Oct.
I also have the Nutribullet Blender to blend up fruits & vegetables for healthy low fat and low calorie smoothies.
