From practical experience, novices prefer elliptical machines. In the gym near my home, technogym has more than a dozen elliptical machines, and every time it goes, it is occupied by girls. The treadmills, spinning bikes and rowing machines nearby are not so popular, and there will always be seats available.
In fact, people who haven't trained for a long time, whether running outdoors or using a treadmill, can't improve the running time and intensity in a short time. But I can already exercise for 50 minutes a week with the elliptical machine, and the weight loss effect is obvious. You can exercise to the inside of the arm where girls are more likely to gain weight, and you can also lift your hips.
