Which comes first, aerobics or weights?

[Guest guest]

Hi all,

I am wondering, when in the gym and doing both weight training and aerobics,

which should be done first? Does it matter whether you get your heart rate

up high for an hour doing aerobic training and then do your weight training

or is vice versa better? This is for the amateur athlete over 40, just your

ordinary person doing a decent work out four days a week. Thanks!
