DRILLs class is appropriate for all fitness levels, and can be done by older participants, and deconditioned participants.  The movements are simple, which allows participants to choose their exertion level.  Encourage participants to work at their own level and to take breaks whenever they feel it is necessary.  Participants should feel free to sit a drill or an entire song out, then join back in whenever they are ready.  This will not adversely affect the quality of their workout; it WILL allow them to work harder and stronger once they join back in.

There are a few points to consider about this class format.  First, ?drills' are tools normally used to train athletes for improved performance.  Many drills are high impact, and may be fairly difficult.  Be sure to show plenty of low impact options.  Be sure to provide adequate breaks.  And be sure to encourage the consumption of as much water as possible.  Pregnant women, older participants, and those who have concerns about high impact exercise should be encouraged to use the low impact options.

Also, because participants will be encouraged to raise their heart rates above the 70% - 80% maximum heart rate zone we must consider those who should use caution with regards to heart rate.  Women who are pregnant or think they could be pregnant should always opt for the low impact versions of the movements because ligaments and joints are less stable during pregnancy.  They should keep their exertion on the moderate side, never allowing their heart rate to get above 140 to ensure acceptable and stable oxygen flow for the fetus.  Heart patients, diabetics, and beginners should be encouraged to keep their exertion moderate.
