I would say so. At my previous gym my PT put together a routine for me of 15min stepper, then arm weights (approx 10 mins to complete), 15 mins x-trainer, then resistance exercises with body weight such as crunchs (2 x 15), bridge (2 x 20 sec), wall squats (2 x 15 - put an exercises ball against the wall, then lean on the ball and use your body weight to do squats) and finish up with some stretching.
The routine worked for me and now that i have had a break for a while (went O/s and moved), i have now joined a new gym and im going on with this plan. Once again it is working.
I just change the kg's or levels if things start to become easy. Indicators for me of things becoming "easier" were being able to hold a conversation without puffing on the x-trainer or being able to take tiny shallow steps instead of deep steps on the stepper.
