>>76244726>looking forwardNo, keep your head neutral, looking at the bottom. If you look forward, you crank your neck up, which is uncomfortable when swimming for a long time, and also you throw your spine out of alignment, which impairs your streamline. Keep your head neutral and push it forward, like you're trying to grow taller, or as if someone was pulling it. This will engage your spine and core and therefore improve your streamline as well as your connections between upper and lower body
>just emptied your lungs before its time to take the next breathNo, no need to do that, it's much more comfortable to have a breathing cycle closer to a normal one, rather than a forced one where you alternatively empty and refill your whole lungs. When you empty your whole lungs, you also lose buoyancy, regaining it when you breathe in. This results in a lot of up-and-down motion, whereas you want to move forward, not up or down.
Exhale slowly into the water, through your nose, like a 3 or 5 out of 10, if 10 meant forced exhalation. Turn your head sideways to come to the air, take a short breath in through your mouth (it won't be a large breath because you've not emptied your lungs, it will be a normal breath like you take at the surface). Return your head to the water, push it forward to restore your streamline and upper/lower body connections.
