Final answer:
In a seated forward fold, placing a blanket or bolster under the knees can help alleviate the strain on the hamstrings.
Step-by-step explanation:
In a seated forward fold, if the hamstrings are tight, it is common to experience difficulty in reaching the toes without straining and causing discomfort. Placing a blanket or bolster under the knees can help to alleviate the strain on the hamstrings and make the pose more accessible. By doing so, it provides additional support and allows for a more comfortable and effective stretch of the hamstrings.
