I think it depends on whether it is simply a matter of controlled movements and postures, or the invoking of spiritual powers by means of meditation or mantras.

The first --- I would say --- is no more pagan than calisthenics or other gymnastic exercises.

In contrast, the latter is communing with undefined spiritual entities, which is forbidden by the First Commandment.
