Hi, height, if you want to put on weight and build muscle mass then heavyweight and low repetitions is good. If you want to build up your stamina and endurance while doing aerobics of any kind then more repetitions and light exercises are good. All the exercises are nearly equally good like running, jogging, skipping, jumping or swimming. All the best.
It is a lot better to do short work outs with higher intensity. If you overdo it you can erase all your progress.
Interval training is the best for weight loss. It means doing some high intensity cardio for five minutes or less. Then you rest, drink water for five minutes. Then do some more cardio. It is good to try and fit in at least 10 minutes of cardio. So if you can only get to 3 minutes of jump rope, rest and do 3 more minutes until you can get some more in.
By the way skipping is the BEST form of cardio around. Remember to do breathing techniques. Never breath through your mouth, breathe through your nose, breathe deep, in and out like your are meditating while you are doing extreme cardio like jump rope. The main thing that stops us is running out of breath. Once you learn to conquer the breathing you can keep on going forever, and the proper breathing, bringing your chest out during inhales, keeping your stomach in, will stop stitches and cramps.
Only drink bits of water during rests because drinking too much water can make cramps come along.
It would be good for weight loss if you team up the jump rope cardio with some toning weight lifting exercises, for all your muscles. Toning is awesome, it will tighten your muscles to make you appear thinner, and in lots of light repetitions it is just like cardio.
For toning you shouldn't lift more than 10 pounds, and even then 10 pounds is kind of heavy.
I'm not on a bike that I can look at how fast I'm going sadly. I'm kinda limited to what I can do. I have a floor, jump rope, basketball but the hoop is broken, a exersisse ball, some 5 lbs little weights, stares, and a bike. I was thinking of going on a long bike ride to target or someplace. It's about less than a hour away on a bike.
Libby, to get a good workout and cut off 10 minutes try this
if you're on a stationary bike with a timer set it for 20 minutes the first minute and a half ride
at about 60-65 rpm then for 30 seconds ride as fast as you can then the next minute and a half ride 60-65 rpm then 30 seconds ride as fast as you can do it for the 20 minutes and a 5 minute cool down. you can do this for just about any routine.
