What's the most effective warm-up before doing my weight lifting circuit?
Is it better to warm up by doing 10 minutes on the elliptical cross-trainer or by doing a set using a light weight before working with your training weight?
Actually, I do both. I run 5 minutes on the treadmill to get my heart active from a long day at the office, get the blood pumping through my body, fresh oxygen in the muscles.
Then, before I work on a certain group of muscles, my first set of the exercise consists of doing 10 - 15 quick reps with a light weight, just to make sure the muscles I will be using have blood pumping through them, and are "warmed up", so I can't injure a muscle.
Next, I take the weight of my exercise and do the workout. Sometimes I do a dropset ( use the heaviest weight first ) or the opposite ( build up the weight - sometimes combined with less repititions )
I don't know if this is the most effective way. I found this to be perfect for my body and muscles.
