"Deloading" is when you work through total body movements as you normally would, but intentionally go lighter in weight and work less overall volume to allow the body time to heal, repair, and actually grow stronger. This is an important element of training when you have been lifting heavy for a while, when you need a break, or if your body is feeling tired / stressed (also optimal for your PMS or menstruation week depending on your body!). A deload week is still energizing while allowing you to take it a little easier during your workouts. It gives the muscles a period of active recovery and can actually increase strength gains in the long run. 

Here's what to do: Choose 2 or 3 max of the total body lifts or the core/conditioning/mobility lift and work through them as usual EXCEPT use lighter weight and perform roughly 2-3 sets of 10-15 reps of each. You should NOT feel muscle fatigue at the end of the set - your muscles are actively lifting & working but NOT straining. 

In general, it's good to take a deload week every 12-16 weeks of training. These can also ideal for a time away/ vacation or similar, if you still plan to workout (and hey if you just need a break or a week off in general - take it!). You can always work bodyweight movements as well in a similar fashion.
