One of the best ways to learn the most info in the shortest times is to watch some videos on youtube.
It gives you the general idea of what its all about and being visual, its a lot quicker than reading or writing it.

When it comes to tapes & glues...... its an entire universe of options and opinions!
Certain types & brands get recommended more than others.

As you intend to go to the gym etc. take in to consideration the ones that are best for being more water resistant.

Good luck.
