A dynamic stretch is an action that warms up the body before a workout or competition.
Dynamic stretches are important because it keeps the body moving and improves range of motion.
I don't think it's not possible to never know when you're hungry, however it may be hard to tell when you are hungry. To tell if you are genuinely hungry, you can check if you are angry, if your stomach is growling or if you wouldn't mind eating anything. You could also drink some water; if you can feel it in your stomach you need to eat.
Hope it helps, good luck! :)
Answer:
step 1. The problem is that there is a miscommunication and you would like to have proper communication going forward.
step 2. You could find a new job, talk to employees, wait the nest day, find someone else to train the new employee while the other one is on leave.
step 3. You have an extra day to get to know your surroundings, co-workers/staff. Some disadvantages would be that you can't do your work and they couldn't find someone to train you.
step 4. Talk to your manager and have her figure out what to do, the manger will then find someone who is qualified to train you and contact tech support to help you log in.
