The biggest difference between a bicycle and a treadmill is ~

Pedal the bike with thigh strength (if the posture is correct).

Treadmills use a lot of calf muscles.

If you are a girl and are afraid of thick legs, don't practice the treadmill!

Unless you have enough patience to do stretching exercises, stretch your muscles after running (in fact, you should do it after all exercises)

When the thighs are thin, the calves are naturally thin!

And when practicing cycling.

Step lightly and practice your speed back (keep it at 70, 80 or 90 per minute).

In addition, the mountaineering machine also has a good effect on hip training.

But ~ if you are a girl, don't be heavy when training!

Exercise muscles ~ not what you want!

I'll add it if necessary! I am a person who goes to the gym and takes many classes every day.

Please accept it, thank you!
