In my opinion, getting north of vag FAST, will have you suffering from injuries again especially since you have done nothing in years. I'm not up to speed on all the new templates that Jim has laid out for people, but originals always work.
You say your concern is putting on mass but ask for a template to lose alot of fat. You need to understand that doing both to an extreme like most people want to do is not going to happen. So let me give you some simple advice that most will not follow, especially those that need it fast and need it yesterday.
Pick the template that suits your lifestyle first and foremost. Most people starting out or starting over are just like people that start eating salads every January, they want to go to extremes instead of just cutting back on the 10 Mountain Dews they drink per day. I'd advise doing a 2 day per week program. This will allow for recovery and plenty of time for doing the other stuff.
Diet does not have to be complicated. Just eat 3-4 times per day and eat good food that you fix at home. You'll be amazed at what simply eating at home and staying away from eating out can do for you. Eat until you are full and satisfied at each meal. Focus on good meats/eggs/cheese with plenty of potatoes, rice, fruits and veggies(ones that agree with your gut and palate). Its that easy. Don't be afraid of carbs. Potatoes and rice are your friends. One of the worst things I ever did was Paleo. Made me weaker than piss and couldn't do anything worthwhile athletically.
Do easy cadio. If you have the means to measure, keep your heart rate between 120-150bpm for 45 minutes 3x per week and you will be golden. If not, when you have to breathe through your mouth just slow down until you can breathe through your nose again. I had not performed any HIIT type cardio in nearly a year and decided to do 100 burpees as fast as possible. I did them under 10 minutes fairly easy while my record when doing the HIIT and nothing else for aerobic work was 11:25. Aerobic base comes first.
Last, don't focus on that outcome(like get to north of vag fast) focus on the process and everything will happen much quicker than you realize. Probably not what you wanted but its the advice I have for you.
