Even though diet is the most important factor in weight loss the role of exercise cannot be minimized. A few pointers :
To achieve weight loss 450 minutes of exercise a week is necessary. To maintain the weight loss you have achieved at least 300 minutes a week of physical activity is required.
Planks as said in the article are a great way to build core strength. Start with 30 seconds and build up to 180 seconds or more if possible. Side planks are one oft overlooked core strengthening exercise.
Check your weight couple of times a week if you are trying to lose weight. Accountability is important in your weight loss journey.
Keeping a food diary or using one of the online apps like MyFitnessPal will help you in tracking caloric intake. This app is intuitive and you can also scan the barcodes of most packaged foods. It makes calorie tracking less laborious.
A good exercise routine should combine at least 30 minutes of aerobics with a minimum of 20 minutes of weight training. Target different groups of muscles each day while weight training. Women should not shy off resistance training nor should they be afraid of lifting heavy. Heavy weights give more definition in a shorter period of time.
Change the aerobic routine every few weeks.
Enjoy your work outs and the results.
