sorry 我有一段时间没有登录了，于是没能看到你的提醒；）

1.后来我才感到气功的确健身

this sentence is a quite "that oral", some key words are omitted.

的确 = truly， indeed

健身， here he wants to say, "healthy", good for your health

------Then I felt it really good for my health that I practise qigong （练气功） 

2. 不会的地方

地方，here means Questions, problems, instead a concret "place"

here "when you get/meet "  or " (questions) occurs to you"  is omitted.

------（当你遇到）不会的地方，我（会will）教你。
