Math questions ?????? working out needed?
well... all you have to do is solve both sides. 2(3x + 4)=2(x-10) 6x+8=2x-20 this was pretty easy. now you have to put both Xs on the same side 6x-2x=-20-8 notice that when a term goes to the other side of the equation, the sign in front of it changes (+8 changed to -8) now all you have to do is the simple math 4x=-28 now divide both sides by 4 (because you want x, not 4x) this leaves you x= -7 QUESTION 2 if the first sheet has pages 1,2,71,72, the second sheet should have 3,4, 69,70 the 3rd sheet has 4,5,67,68. now u count on using the first page number for each sheet 4th=6,7 5th=8,9 6=10,11 7th sheet = 12,13 8th sheet=14,15 9th sheet= 16,17 10th sheet=18, 19 now if we go back to the start of the question, the first sheet had 1,2,71,72 the second sheet had 3,4, 69,70. adding the first page number and the last page number of every sheet should get you 73. so in the 10th sheet (where we found page 19) the first number is 18. 73-18=55. therefore the 10th sheet has page numbers, 18,19,54,55 and therefore the sheet with 19 also has 18, 54,55 QUESTION 3 this doesnt make sense. im sorry, but i dont understand it. hope this helps!!

These are but a few tips you should keep in mind if you want to benefit from your home gym program.

Can you get ripped from working out at home?
As other posters have said, you need to eat a serious amount of food to battle your fast metabolism. Make sure you eat at least 500 calories above your daily maintenance calories. Take a protein shake 30 min before you workout, and another no later than 30 min after. In terms of your exercise routine, it's unlikely the dumbbells you have at home will be heavy enough to tax your muscles (or at least you'll outgrow them really quickly). Stick to a proven bodyweight strength programme. Have a look at the basic routine at http://www.StartBodyweight.com Since your goal is hypertrophy (muscle building), not strength specifically, change all the rep ranges from 4-8 to 8-12. This is commonly thought to be a better range for gaining muscle. Stick to rest periods of between 1 and 2 min. I hope this helps!
Can you get "built" by only working out at home?
Yes you absolutely can get built by working out at home. You just need to have the motivation and willpower to force yourself to stick to regularly doing your exercise regime. Here is a free insane arms building video book that has many exercises you could do from home http://bit.ly/InsaneArmsThe other things that you really should get are a weights bench that you can put at different angles and possibly a barbell and a piece of rope to tie weights to, then you’ve in effect got a full gym set up. Good luck!!
How can I lose weight by working out at home?
I have lost 20lbs. This is what I did: Ate healthy and limited myself to only two snacks a day. Jogged the mile 5 days a week. I started with running a quarter, walking a quarter, running a quarter, etc until I ran the mile. Every week I ran more and more and walked less and less. Until I finally could run the whole mile through. Once you get into the habit, it becomes natural and you get better and better. Good luck!
