Get up and sleep every day and do 30 pressure sticks. Does fifty sit-ups work? Want to exercise. Will it be too little?

Enough strength. But remember that quantity is not the key to fitness. Slow down. Lie on your back for 3~5 seconds.

The layering is also slow.

Secondly. Short interval multi-group number. A group should not be too big and comfortable.

A glass of milk is best after 20 minutes of exercise.
