This is what I've been doing to prepare for my early June trip. I started started in January with the goal to lose 25 LB by June. I'm down 16 so far. I started with walking a few miles 2 or 3 times a week. As the weather improved here in MI I walked more distance and more often. I threw in the occasional dumbell workout (30 minutes or so). Now I am running, up to 4 miles, 3 times a week and walking 6 miles when I don't run. More frequent dumbell works too. I'm planning to kayak on Saturday, then try for a 5 mile run.  I paddle when I can, only a total of about 10 hrs so far this year. Recently I've been carrying my canoe a few times a week on a trail through the woods on my property for about 1/2 mile. Tonight it is mountain biking.

If my work out gets too routine or regimented I get bored. I like to mix it up as much as possible. I've never been a big fan of keep track of times, weight, reps. etc.

Also I've been eating lots of fruit and veggies and drinking less beer  :( ....but I have enjoyed a few sips of Jameson.
