Since your client is new to exercise and not in great condition, I recommend low intensity base building cardio exercise before incorporating intervals. The base building cardio will better equip her for intervals and better her conditioning for resistance training and activities of daily living. Over time you can gradual introduce intervals into her base building cardio exercise.
Take a look at the included link from NASM. Great information on taking new clients through stage training for cardio.
Hope this helps!
for a new client like that I would not start with a strength / cardio interval program. I would recommend for her a cardio routine that initially may not be more than walking and work with her to develop correct form in her strength routine.
I’m with Karin & Louis. Just get her going with some easy CV exercise & include some basic strength training exercises – focusing on form. When she gets the hang of things after a while, then start mixing things up if you want. At this beginning stage, don’t worry about things like interval training – it’s too much to process. I would just keep it simple for now & let her experience some success – then progress from there. Good luck Kelly.
I agree with everyone else. Keep it simple, build a good cardio base and establish correct form on strength. As she progresses and builds confidence in herself then think about including interval training.
