I'm always happy to answer questions for anyone on here, I keep tellin' ya that
I feel kinda guilty because this is your job and I keep asking you for advice for free....sorry sweetie!:lol:
Seeing as I'm not working as a PT at the moment it's good to keep my mind still going with it!
1. Seeing as you're female, if you increase the weight and keep the amount of reps you're doing high when you want to maintain, I don't think you'd really notice that you're getting "too bulky". Unless you do insane amounts of training and take lots of supplements etc, you won't bulk up. I know you want to maintain, but it's good to keep increasing your weights because as I said, you'll get bored and your body will just get used to the same weight and it'll be pointless even doing it! So I'd keep increasing the weight but just make sure to keep the reps high
2. 18.5 is a healthy BMI, yes
18.5 - 24.9 is the healthy range
18.5 is the lowest end of the scale though, anything under that is said to be underweight. (I just wrote underwear then hahah
) Butttt we all know the BMI can be a bit of a crock!!
3. It depends whether you're happy with the results from your weight program. If you are, you can keep it the same, just make sure you're upping the weights. It's good to shock the body once in a while by introducing different exercises, but as the old saying goes - if it ain't broke, don't fix it!
4. It's up to you whether you have a week off both cardio AND weights. Muscles get used to death in cardio too, so if you want a full recharge it would be best to take a week off both, and just do some light exercise like walking etc. But you'll still get a recharge for doing weights if you keep doing your cardio
A week off is definitely a good idea, or even a "light week" where you don't do as much as frequently.
Hope this helped
Any more questions, just ask!
