Roots

打拳不遛腿，必是冒失鬼

Training boxing without strolling with the legs, certainly a reckless person.

Or

Training boxing without stopping on the legs, certainly a reckless person.

Legs and up to the waist are the roots, the essential part of training.

遛 means to stroll, to take a walk, training the legs comes through relaxation.

遛 also means to stop, training the legs comes also through static postures.

Hence 遛 is a reminder that stressing on the hands movements is not going for the essential.

遛 is made of 卯, 5-7 a.m, 田, field, to farm, and 辵, to walk. 5-7 a.m is one of the preferred training times for internalists.

A great part of training the legs is flexibility, hence the often called basic trainings, "基本功".

A great part of flexibility and 會陰 (Huiyin, an acupoint or more simply the perineum) training is holding a stretch for a very long period of time, sometimes hours*.

Some old practices used to have a "just on one feet" version of their routines.

Such saying shall be linked with 未学功夫，先学跌打, "Before studying skills one shall study acrobatics".

*This also used to be part of the "sleeping practices" in the old days.
