Enjoy your merits of worshipping Buddha. Worship Buddha is not only the best exercise, but also a method of spiritual practice, which can eliminate karma, increase blessings, develop wisdom and so on.
I've been worshipping Buddha recently. At first, I found it difficult to worship even 50 times. The hardest part is actually in the beginning I am deeply encouraged by reading other people's deeds, so I insist on worshipping one by one. I am not in a hurry and don't put too much pressure on myself.
Sometimes because of laziness or other reasons, I used to worship only one hundred times a day and only two hundred times a day. Later, because I was used to it, I could worship more than 300 times a day.
I don't worship Buddha very fast, about 200 times an hour. Sometimes I get up early and worship a hundred times. When I have more time in the evening, I worship a few times more.
Counting method: you can download a counting app with your mobile phone and put it in front of the mat. Click on the screen of your mobile phone and it will count itself, which is very convenient.
I wish you diligence, happiness and wisdom!
