Is cardio the best for weight lose?:
This is difficult to answer without giving you an exam. "weight loss" in the fitness world needs to be re-written to "fat loss" I have GAINED weight before and actually have been healthier, lost a lot of fat and had lower cholesterol. Remember muscle is denser. So 1lb of fat takes up FIVE TIMES the space 1lb of muscle does. How much your body is pulled to the earth and makes the scale read is irreleavnt. These are things that will make you get in much better shape:
1)Loss of fat. - You don’t want a fat ratio less than 9% and no greater than 20% So find out your fat ratio. (bodyfat percentage)
2)Don’t use weight as a measurement of your progress. You will discourage yourself and think you aren’t making any headway and give up. IF the scale is going to lower (which it will if you are overweight) it will take some time before you see those results.
3)Be realistic. Those people on that show have a lot of time and you have NO idea how much time has passed when you see the results they get. It’s all condensed. Also they are handheld in what they eat, HOW they work out and how much effort they put in is "drill instructed" by their coaches..
You are alone, free to eat as you please and nobody is going to prod you along the treadmill… Hence you might not rocket to the 6 week plan they claim to have "earned"
Is running up and down the stairs, jump roping good exercise?:
Yes. Any exercise is good but those are good for a few reasons.
1)cardio
2)Easy to do anywhere so compliance will be high
3)Highest impact for the effort exerted
How many times a week should I workout for and for how long?
At least 3 times per week and as long as you put in 30 minutes (or more) each session you are going to do great!
My fore head was sweating!! Do you think that was a good workout?:
Yes. Sweat is a great indicator of you expelling calories. The more you burn, the better you will get at this!! You do NOT want to be dripping like you are in the shower. It should be a mist and nothing more. It’s a KNOWN fact that going beyond your "burn index" heart rate wise is actually a complete waste of time. If you can get to a gym only one time, have them do a "bod pod" workup on you. This will find out what your "ideal heartrate" is for burning fat. 
it’s WAY lower than you think and much easier to achieve than building mass (instead of losing fat)
does it make you feel that way too?
Generally speaking, any accomplishment makes me feel good. Yes it does make me feel that way. Energy, happiness they’re components of a good fitness regimen..
Lastly, you didn’t ask but FOOD.
Intake is at least 60% of the battle.
If you took two people who sat on a couch all day and did NO EXERCISE and one ate what they wanted and the other ate only what a specialist (for nutrition) fed them, the person being fed would LOSE weight.
Go online and find sources that will provide meals and ideas for weight loss (fat loss) in mind.
Atkins is the best proven because of compliance.
A lot of people on here will say "eat this or eat that"
but if you aren’t all about salads and cottage cheese you simply won’t obey the plan.
Atkins has a high success rate because people aren’t "giving up" any of their favored foods. Hence MAJOR compliance
Hope that helps.
I’m not sure how much i weigh tho. How Long should I work out for? I think That If my Mom does agree, That I’ll Mostly workout during a week,Take breaks On weekends. How Long Till I see Results? I’m 5′4 & I think, 130-145.
About How Long Will It Be for Weight Loss Results?
What a great weight loss question:
Cutting calories+working out = DEFINITE and wayyyy noticeable results. You may not see them the first couple of weeks but trust me, you WILL see them before the 1 month mark hits and maybe even sooner! it just depends how much you put into it because the more you put, the more improvement you will see. There’ll be times that will be hard because not everyone around you may watch what they eat and you’ll be tempted to give in but stick to your healthy diet and you’ll be glad in the end!
Good luck to you!
