thanks coach @Meredith Barrington , i will practice this , as i always feel like i have a very shallow breathe. i have another follow up q. For us to be able to swim, we are always being taught to learn to breathe in thro our mouth but not our nose when swimming, this is the reason why i mis-interpreted the relaxation excise shall be breathing in thro the mouth too. May i get some insights from you re this? many thanks!!!
