While a few opportunities to deepen into a posture may be effective, in general it is advisable to avoid long holds within an asana (which tends to be more appropriate for experienced students).
Instead, consider including dynamic movement and repetition for newer students.
Alternate One-Sided Movements
It’s advisable when teaching beginners to teach relatively few one-sided poses in a row. That is, teach only one to two poses before switching sides.
For example, more advanced students may enjoy a flow of Warrior 2 Pose into Revolved Warrior into Side Angle Pose into Triangle Pose on one side. This is not advisable for beginners. Instead, teach Warrior 2 Pose on one side, taking plenty of time to set up foundation, and then teach it on the second side, for instance.
