Mondays & Thursdays I do dumbbell curls and lunges, leg press and curls, tricep press, lat pulldown, rows, and ab leg lifts.
Tuesdays & Fridays I do bench, incline, and military press; jump rope; push-ups; crunches; and various ladder exercises.
Wednesdays I do cardio. I also do planks every day.
I definitely agree with you about feeling better and having more energy. Of course, immediately after working out I feel weak and whatnot, but after about half an hour I feel great!
