they looked like something with a max mph of like 50; any idea what the brand name was? they were NOT vespas or gopeds of any sort...


Answer
You saw some real Mopeds. The moped was designed (and required by regulation at one time) to have a 50cc engine or less, pedals as well as motor, top speed not to exceed 30mph (35mph in some places) There were literally hundreds of producers from Italy to China making them (or at least selling them, as many were produced by a single company and marketed under numerous names.) The term Mo (for motor) ped (for pedals) pretty much described them. The concept was for a small commuter vehicle that did not require licensing and fell under the same legal standing as a bicycle. Unfortunately many municipalities decided that they were motor vehicles and started requiring licensing, helmet wear and registration costs that made Mopeds not worth the aggravation, and so they fell by the wayside. Also the 2 cycle engines used were not very reliable and so most have long since gone to the dump.

Elliptical workout? Does this sound right?




Anna Shaw


I'm 13, 5'5', female, and weigh 143lbs. My elliptical does have a heart rate monitor but it doesn't know my weight. However, after an hour it tells me I burn about 800 calories. is this right? Or should I assume I burned about half of that? Also, I go at a moderate speed.

If I'm not burning 800 calories, can you tell me about what I am burning?



Answer
Yes, you should assume you burned half of that and I bet you did not even enjoy it so much at the beginning. Thank goodness for your body (after 30 minutes in your THR zone) when it starts releasing chemicals to prevent pain and hunger so you can keep going. Those natural chemicals (endorphins, epinephrine, serotonin, and dopamine, among others) make you feel so goodâ¦happy, energetic...

I can tell you (90% sure) that at 143lbs, youâre not burning 800 calories using an elliptical for an hour.
I donât use elliptical machines but as I understand, they have different strides per minute and resistance settings.
A moderate speed would be, I would guess like a 100 strides per minute (out of 170) and a 7 resistance (out of 20), then you would burn 387 calories in an hour at 143lbs.

Do not rely on inaccurate machines' readouts because theyâre malfunctioning (the readout is often that piece of junk Made in China as a faulty readout wonât physically hurt people) OR because you cannot input enough info to get the proper results (gender, age, weight, speed, fitness level, THR zonesâ¦) OR because you did not reset it and the person using it before you was different from you OR because you made a mistake while entering data OR because itâs a common marketing practice for the manufacturer to deliberately misscalibrate the readout (up to doubling the caloric expenditure) to make people believe that theyâre burning more calories on a machine (when they donât) so theyâll be more likely to buy it.
Itâs like clothes manufacturers putting size 4 labels on size 6 clothes just to sell more of them (donât rely on labels, just your body measurements).

Nowâ¦how much fun did you have using an elliptical for an hour?
Be honest.
You wonât last long if you donât enjoy physical activity or at least not dread it.

As a teenager, things were different and I was skinny as a stick (until I got to be 16yo and blossomed, I was a late bloomer), I had no idea about exercising and gym machines or what was my BMR and calorie intake/expenditure and did not own a bathroom scale. I did not even have a bathroom but I had a shower tub in the kitchen, which was a big improvement over standing up in a bucket. Now I have 3 full size bathrooms...be careful what you wish for as you might have to clean it!
I did not have a phone or a computer or watch much TV and I was not exposed to restaurant food or junk/packaged/processed food. I spent the afternoon of my weekly no-school day peeling veggies and simmering the vegetables for the week side dishes.

I would go on 100kms/62.5 miles bike rides, at a leisure 12.5mph speed (2.5 hours in the morning, same in the afternoon) and had to eat 2,000 more calories, above my BMR + growth for physical activities (62.5 x 32 calories per mile = 2,000 calories for physical activity)

You have a good height (Iâm 5â5 too and itâs a good height) but how come youâre overweight at the 89th percentile??
Youâre old enough to learn how to cook and take charge of your diet if youâre so unlucky that nobody will cook great tasty healthy meals for you.
At 12, I could handle kitchen knives to cut fruits/veggies/meats without cutting myself and bleeding all over the kitchen.

You need to have fun with your friends and be involved in sports, not use a boring elliptical machine for an hour.

If I would need to lose 800 calories, I could use my stationary bicycle, at a leisurely pace of 12.5mph (lower end of the THR Aerobic Zone), 32 calories per mile and burn 800 calories in two hours covering 25 miles while zoning out as youâre sitting so itâs a non-weight bearing exercise and your body weight does not matter, and youâre not on a real bike having to wear a helmet and watching out for trafficâ¦so you can watch a movie or TV shows or read magazines or articles onlineâ¦

I would surely not use an elliptical (youâre standing, right? Iâd rather take a seat to burn 800 calories).
