2, it is best to go to the gym with the guidance of a coach (precautions, equipment, nutrition and catering). If you are at home, simply equip dumbbells, arms, etc. You can also do push-ups and squats without them. There is no trick. Pursuing standards is practice. You have higher requirements for yourself in this respect. Push-ups can be arranged in front of dumbbells, or one every day.
3, for example: push-ups are fifteen a day, and you should be able to do thirty in two weeks.
The strength is growing very fast. The key is whether you can persist for a long time and have the confidence to do it.
I wish you reach your training goal as soon as possible!
I hope it helps you! Hope to adopt!
