Weights in between?

Question....

I was doing weights 3 x wk then started training with a PT (don't start on me people.... this isn't a debate) so I stopped weight training whilst doing the PT session (2 months worth)

Some of the things I do in the PT sessions are lunges, squats, ball work (12lbs), sprints, pull ups, sit ups, push ups, ab/side stabs ect ect

I want to know if you think it is okay to do weights on the off days as I know I am meant to let my muscles rest for a day in between but am unsure if the PT sessions really count as a session in which my muscles need a days rest from (don't get me wrong - I enjoy these sessions and find them very challenging physically).  I just remember some weights sessions I couldn't walk the next day  whereas I only had that from the first PT session.  My muscles get a little sore now, but no were near the extent they do when I was weight training. 

The weight training I was doing was nothing in comparison to the level of weights of most people on here, as I only got up to about 33lbs at most in some exercises, but I was steadily increasing that. (started at 11lbs and up to 33lbs in approx. 6 wks).

So to summarise.... would it be okay to do that kind of weight training on the inbetween days of the PT sessions?

If you "find them very challenging physically" then doing weights inbetween won't be enough rest. So when you do lunges, squats, etc with the PT it's all body weight for the last 2 months? I think maybe you should talk to your PT about adding weights into the session with the stuff your doing. I'd find body weight lunges and squats not challenging enough after two months too. Or do the weights by yourself on the same day as the PT sessions, so your getting the rest day inbetween.

I don't think it is a good idea to strength train between sessions.  I know that you said you find your PT sessions challenging but you also say you are not seeing much progress re: gains in strength.  The fact that you are considering working out on your off days makes me think that you are not much benefit in this area right now and need to talk to your trainer as butterfly said to increase the intensity.  Here is an excerpt of Steve Maxwell's article on 12 Reason's to fire your personal trainer:

11. He's letting you get away with murder--and you know it.
Sometimes trainers put clients through ridiculously easy workouts (they don't push you, permit sloppy form, stick you on aerobic equipment while they just talk to you) just to make some easy money. They don't progress you or design new programs. Or they switch up your program so frequently there are no meaningful gains made. They don't admonish you for diet infractions or missed workouts or touch on any seemingly unpleasant topics because they're interested only in your money, not you and your progress. A true fitness professional will call you on your bullsh!t because he's about earning the money he's paid.

Thanks for your replys.  I know I am getting stronger as I can now do mens push ups and the girls ones are quite easy.  She does push me to muscle fatigue but it just feels different to when I was doing weights.  She also has started bringing in weight discs to use in lunges and squats (22lbs) but doesn't do this all the time.

I guess maybe because she incorporates cadio in there as well it feels different?  I might try a week with doing weights as well just to see how I go.  If it is too much I will stop as I do notice a difference when I do PT sessions x 2 days in a row.

thanks again for your insight...
