You don't have to practice every day, so your muscles will get hurt. It is good to practice five days a week!
I'll give you a fitness plan: run a little warm-up before exercise every day, then practice your arms with dumbbells for 4 to 6 groups, and the rest time between each group should be controlled within 90 seconds.
Then practice abdominal muscles. If you are doing supine exercises, you should also practice in groups. How many can each group do? Keep it at 4 to 6, and you can do it, too. The interval rest is also within 90 seconds, so the effect of training for two months is very good.
Give it a try!
