What to Do First: Cardio or Weights

It is the age old conundrum - cardio before weights, or weights before cardio? For me there is no clear cut answer or protocol. So I thought I would share my internal debate on the matter.

Reasons to do Cardio first:

  • I am planning to do a long cardio session and I don't want to tire out my legs before running for 60 minutes.
  • I am just planning on lifting weights with my upper body and they will still feel fresh after my cardio session.
  • The weight room at the gym is really crowded.

Reasons to Lift first

  • If my focus for the workout is strength training, I will warm up and cool down with a little cardio, but spend most of my time lifting weights. This way my lifting form is not compromised by my tired muscles. I think this helps prevent injury too.

  • Here is a scientific reason that I factor in to my decision making process: Lifting weights first can boost your fat-burning power during the aerobic part of your workout since it can deplete your "quick burst" energy (glycogen) stores. This means when you do your cardio workout after lifting weights, you'll likely burn less glycogen and more stored fat.
  • If the cardio room is really full, I will lift weights first.

Sometimes I skip the entire debate and just mix it all together with some circuit training. And you? Which do you do first? Lift weights or cardio?

I love that we are having this conversation :) I was always a "cardio first, then weights" type of girl but then the last few times I was at the gym I overheard trainers telling their clients in their sessions about how they can burn more fat if they do the weights first (just as Fit mentioned above), so I've changed my routine! Like most of you ladies, I typically alternate days but there are times when I do both in the same day. I'm a big fan of pilates, so sometimes I'll do my pilates moves on my ball with my stretch band for tummy and strength training, and then my cardio. I love it! :D

I love weights and hate cardio.. so I do it first like taking a band-aid off and then start the fun stuff..when I've eaten a lot that week, I'd do 45 minutes on the elyptical..if not, then I'll just do 10 to 15 min and then start weight lifting

In general I do a quick 15 minute warm-up usually switching up 3 types of cardio activities, then weights, and then cardio. I allow 48 hours between weight lifting. When I lift, it is circuit training.I run 15 minutes on lifting days and 45 minutes on non-lifting days.Monday: 15 minute cardio, circuit training, tennis lesson, ballet lessonTuesday: 45 minute runWednesday: 15 minutes cardio, circuit training, tennis lesson, ballet lessonThursday: 45 minute runFriday: 15 minute cardio, circuit training, tennis lessonSaturday: Something fun like more tennisSunday: Nothing!

I do weights first because I'll get too tired if I do cardio first. I know my body and it throws in the towel after 45 minutes of cardio no matter what!

I have had this internal debate with myself for years. I havn't found a clear cut answer. However, I circumvent this by doing Cardio in the AM and then weight lifting in the PM. I hate lifting in the morning and by lifting in the afternoon I get lots and lots of eye candy as motivation to keep going!!Also if it's an "off" day I can just do yoga in the morning and still get a great stretch and feel more focused during the day, it's my form of active recovery. =)

I mix it up: 10 mins. on the Cybex stepper, then all my weight lifting (I alternate each day between abs and upper body weights and legs/lower body weights,) then I finish with 20 mins. on the elliptical and 15 on the treadmill doing a running/speedwalking mix. I wish I didn't feel so pressed for time whenever I'm there!
