 Rc tools for fitness tracking

+## basal metabolic rate (BMR)
+
+Computes the BMR using the Mifflin-St. Jeor equation.
+
+	# bmr for a 33 year old male whose height is 180cm and weights 92kg
+	% bmr 92 180 33
+	# bmr for a 27 year old female who weights 67kg and is 165cm tall
+	% bmr -w 67 165 27
+
+## weight tracking
+
+	# today the scale marks 80kg (careful with obsessing over this)
+	% weighin 80
+
+## default session file
+
+The `default.session` file shows a repetitions-per-exercise table,
+matching the order in the `exercises` file, ready to be selected and
+sent to a [rio(1)](http:/man.9front.org/1/rio) window right after
+starting a `workout`.
+
+## about weights
+
+In weightlifting exercises where (dumb|bar|kettle)bells are used, the
+weight isn't tracked.  It should be up to you how much you are lifting
+and at what pace.  Feel free to extend the scripts to match your
+training procedure.
