hi all, i realise this is a question asked a lot and i've read heaps of the other threads but would still like some clarification.
i'm looking to lose 10 - 15 kg (20 - 30 lbs) in the next 3 - 4 months. i've cut my calorie intake, joined the gym and recently had an appointment with a trainer in which he drew up a workout plan for me. basically, he's got me on strength training 3 days a week, whole body work out, 3 sets of 15 reps with 30 seconds between sets. i assume this is to incorporate more of a circuit training feel into my workout and keep my heartrate up, thus having a cardio workout also.
the thing is, i asked him about cardio workouts and he said that i didn't really need to do much, just go on walks with my mum every couple of days (we usually go 2 - 3 days a week for about 40 mins, at a moderate pace - as in we are still able to gossip while walking!) and basically do some "light" cardio on my non-weights days if i want.
being someone who has always thought cardio is absolutely crucial to weight loss, this has thrown me for a huge loop. i'm confused by his "if i want" statement in relation to cardio, since this makes it seem it isn't really necessary but if it makes me feel better i can do it.
so, what does everybody do cardio-wise? is it necessary? are my moderate paced walks enough? i don't really want to go to the gym every day or even 5 days a week but i find it harder to jog outside (harder to time myself really, on how long i'm running) because i prefer to do interval work when i run/jog/walk for exercise and not enjoyment (which is what my walks with my mum are!). i've been doing some interval work on the treadmill for about 15 mins after my weights sessions (which last about 30 mins) but i can't do more than that because i feel so exhausted after the weights and then the intervals. still, i feel like 45 mins 3 days a week will not get me to my goal!
anyway, opinions are greatly appreciated!
