When should I start strength training?

Start strength training now. Muscle burns more than fat (I don't remember exactly). 2 days a week spend 15-20 mins of your cardio training doing strength/circuit training. It's amazing what you can get done in 15-20 mins and hit all the major muscle groups!

Editted to add: you can easily do things like using canned items or plastic water bottles for weights at home, squats during bathroom breaks at work, etc...no need to always do it at the gym!

I would start now, when you build lean muscle is burns fat, it also helps your body stay toned to help with things like loose skin etc.

I read a blog post somewhere about weight loss and strength training, and the author made a good point: you aren't likely to gain more weight in muscle than you lose in fat if you have a lot of weight to lose... to put numbers to it, say you want to lose 50 lbs (of fat, obviously)--you aren't going to gain 50 lbs of muscle (unless you're taking steroids or something like that) in the same time frame as you would lose the 50 lbs of fat. Sure, it might slow your weight loss a little, but the reality is that muscle burns more energy than fat at rest, so you're doing yourself a favour by putting on an additional few pounds of muscle--it may in fact slightly speed up your weight loss because you'd be burning more calories sitting at rest with a higher amount of lean body mass. Like Nina74 said, start as soon as you can!

i would try jillian michaels 30 day shred at home if i were you and its only 20mins - so you can fit it in any time like do it when the dinner is in the oven lol

start now! i have trained many clients similar to your sched. you're doing a fantastic job with cardio and you can add strength training (ST) 2-3 days instead of your cardio days. the calories you burn in the 45 mins of cardio have your body burning cals 4-5 hours after you leave class. if you do 45 of strength training, you're body will take 24-48 hours to repair, meaning your body will be burning calories the whole time while repairing. that is the diff between 45 mins of cardio and 45 mins of lifting. muscle does not weigh more than fat. they both weigh the same. a pound of muscle is smaller than a pound of fat. ST will build muscle and shred fat. you need both cardio and ST along with clean eating to balance out your body and acheive the goals you are striving for. you may email me at vickilynn333@hotmail.com if you want more details. good luck and great job so far!
