Now obviously freehand climbing (with no rope) is more dangerous, so I don't recommend it for amateurs. If you are new to rock climbing I suggest sticking to easy to climb areas, indoor rock climbing, or climbing with all the right gear and a friend who is an experienced climber.
As exercises go rock climbing is fairly frugal and isn't going to cost you a lot to get into it. Compared to a 1-year gym membership it is quite cheap.
Wow! That girl drinks a lot of smoothies!
Personally I add skim milk to my smoothies for the added protein and milky goodness. Sometimes I also make high protein smoothies by adding whey protein powder.
My favourite smoothies to make are strawberry / raspberry with vanilla flavoured whey protein.
