So I am starting over at my highest weight and lowest level of fitness that I feel I have had since I was 20. I am 25 now, 5'4.5, 142. I have gained and lost weight my whole life, but have not focused on fitness enough. My "happy weight" before was around 125, but I don't mind being a little heavier if I have less fat but more muscle. I am absurdly out of shape now, people! Since I know that many of you amazing people have had amazing results, I want to hear your ideas about the fitness plan I have created for myself! I plan to use this plan for the first 2 months and reevaluate once I get stronger and have more resources available. Encouragement, criticism, other ideas, are all equally welcome!

Exercise per week:

5x 30 minute sessions split between 30 day shred (which I had great results with before I had to ship my TV and weights overseas- will get both back this week) and kettlebell/weight training) So, 3 days of one, 2 days of the other.
?, k
4x 10 minute ab specific workouts (my own mix of 8 different exercises- these are the one thing I actually truly enjoy)

2 hours per week of light but fun extra activity- walking, surfing, throwing around a frisbee, random jumping jacks, squats, splashing around in the pool, etc.

Since I am only trying to lose around 15 lbs, I am planning to do TDEE- 18%.... which begs another question, could I safely assume "light activity" instead of sedentary with that workout plan to calculate?

My plan is based on my current resources, my available time, my idea of what I can realistically commit to. But I would love someone who has more experience or knowledge to give me their input! The only things I am not willing to do are eat lower than 1400 calories (this has never worked for me in the long term), workout 2 hours a day (don't have the time) use diet pills, or anything that will harm my health.

Would add that my food intake is largely lean protein, fruits and veggies, nuts, and the occasional beer out with friends.
