Are You Dehydrated?

A great little "how to know" from Oxygen magazine:

Postworkout thirst, goosebumps, shivering, fatigue and an elevated heart rate are some of the signs that your training may be leaving you dehydrated.  To determine whether your bouts in the gym are leaving you parched, step on the scale before and after a workout to calculate your percentage of body-weight change.  Follow this guide from the American College of Sports Medicine to determine whether you need to up your water intake.

Hydration Level                  Body-Weight Change (%)
Well-Hydrated                                    -1 to +1
Minimal Dehydration                        -1 to -3
Significant Dehydration                    -3 to -5
Serious Dehydration                         -5 or higher
