Losing weight in the gym is still relatively fast.
I suggest you do the following:
1 It is advisable to exercise 3-5 times a week.
The intensity is gradually increasing, (the time and load of exercise) should be gradual, giving the body an adaptive process, not excessive.
I suggest you do some aerobic exercise and equipment every time you exercise.
1) Aerobic exercise: You can consume a lot of fat, but you must ensure the time.
"Running" (running for more than half an hour at a time) doesn't need to run too fast. What's important is to continue. The heart rate is about 140- 160.
If at first, you feel too fat to stand, you can start with a "quick walk" (preferably about an hour).
2) The instrument belongs to anaerobic exercise. Can help you tighten your muscles.
Men use dumbbells (to exercise their upper limbs). You can also do pull-ups. Maybe now is not the time for you.
Barbell (exercise lower limbs and legs), but in the absence of protection, try to choose "leg flexion and extension device", some of which are called "pedal device", which is safer.
Exercise the waist: Be familiar with waist wrenches (rotating waist muscles) and "sit-ups".
Note: when making strength equipment, remember not to be too heavy, provided that you can bear it. The specific situation varies from person to person.
Another point is crucial: exercise should be combined with a reasonable diet to lose weight. Exercise consumes a lot of physical energy, so you must not go on a diet, but you must control it and not add meals to yourself intentionally or unintentionally. Just eat normally.
Also, after exercise, you should replenish proper salt water in time and drink sports drinks. But remember not to drink a lot of water when you are sweating too much.
I know a little about fitness. This is my little suggestion. I'll stop here and hope it will help you.
