Rigglin come and join us on the 'grab your tuna' thread. It is mainly for people doing the Davina 7 Minute exercise DVD, but we welcome all. It isn't competitive, more encouraging. We don't really talk about weight loss per se or massive achievements. We discuss the 'small differences', for example we will cheer on the person that did one proper push up, or the person that got through the a full section for the first time without stopping, or indeed the person that now realises that they can climb the stairs without requiring oxygen at the top!
You could do you walking and a bit of this DVD, the minimum time spent on doing a routine is 3 mins warm up and a 7 minute routine = 10 mins, but you can build it up as you wish. It honestly isn't hardcore, but it is good for allowing variety into your exercise routine. Davina recommends using the DVD alongside another exercise such as running.
My exercise routine is this DVD on 4 - 5 times per week and swimming 1 - 2 times per week and I cycle to and from work (10 mins each way) 4 x per week. I don't run because I really dislike it.
As others have said, start with your walking and increase the pace, maybe by walking at your normal speed, then every 5th minute of walking, power walk between lamposts. This can then develop into a run, then reduce the time of walking to running etc. That is, if you like running.
I think the key thing with exercise is finding something that you firstly enjoy, and secondly what you can feasibly fit into your normal day without it being a complete drag, requiring major reshuffling of your normal routine or engagements. Make the conscious decision to make and change and just get on with it and accept there might be hiccups on the way, but you will just return to what you were doing.
