Aerospace engineers design aircraft, spacecraft, satellites and missiles, according to the BLS. In addition, these engineers test prototypes to make sure that they function according to plans.
1 Try a deload every six weeks or so. 2  Most serious coaches recommend three or four weeks on, one week off to their intermediate and advanced trainees. 3  These are people competing in strength sports and pushing serious weight, so you may not have to deload quite so often.
Typically, deload weeks are regularly scheduled â most commonly every fourth week. Despite this, I've argued against the idea of a planned back off week, since you'll inevitably have unplanned deload weeks due to unexpected illness, injury, and/or outside obligations that always seem to pop up without warning. One flaw of this approach is that it's probably better to be proactive than reactive.
