A riding mower may be faster, but you won't break a sweat quite like you do when using a push mower. Powered edgers are heavy to hold, so all the upper body muscles are engaged, while the repetition of using hand clippers targets your forearms. When the mercury soars, keep in mind that thirst is a sign that your body is already dehydrated. Stop to drink water well before you even think you need it (not to mention before and after the project).
