I’m on Day 21 of this challenge, and I haven’t missed a single day! This is the first time I’ve ever been able to stick to a workout challenge for more than 5 days, and I want to thank you, Cassey. You are inspirational and so fun and you understand beginners better than any other fitness instructor out there. Thank you thank you THANK YOU for this challenge, and never stop!!!
HOW TO DO IT: Start in a high plank. Push your hips back without arching your lower back until your knees flex to about 90 degrees. Pause for a beat, then explosively extend through your knees, ankles and hips while also pulling with your upper back as you lower into the bottom of a push-up. Keep your elbows tucked into your sides to protect your shoulders. Skip the push-up and just maintain a hold if you need it to be easier.
Flabby arms are something a lot of us have to tend to. If you find yourself buying a sweater or cardigan to go with your tank top or usually opt for the long-sleeved dress, then you’re not alone. Usually a result of genes, general excess fat or just ageing, it seems difficult to lose arm fat. The fat in our arms accumulates mainly around the triceps – the muscles on the back of your upper arm – and are prone to getting flabby if not exercised regularly.
At least 35% of all cancer deaths may be related to overweight and lack of activity, the Seattle Cancer Research Centre has found. Exercise is believed to speed the passage of food through the colon, thereby reducing the amount of time that any toxins are in contact with the body. Overweight people also tend to have more insulin, which promotes the growth of tumours. For women, exercise reduces the level of oestrogen, a hormone linked to breast cancer.
FIT TIP: To trim your tummy, do fewer crunches and more planks: Begin on all fours, hands under shoulders, knees under hips, then lower forearms to floor and extend legs straight behind you, balancing on toes. Keeping abs engaged and back flat, hold for 30 seconds; do 10 reps three or four times a week. Limit crunches to no more than three sets of 15 at a time. Anything beyond that isn't doing you much good, experts say.
Although the cardiovascular effects of exercise are partly related to inflammation, they still deserve their own category. Exercise is one of the best-illustrated things we can do for our hearts, and this includes markers like blood pressure and cholesterol, in addition the physical structure of the heart itself, and blood vessel function. Studies have suggested that 30 minutes per day is good enough to keep the heart in shape, while others have suggested we do more than this to get a real effect. Some have found that light activity is even enough to help the heart, but not all research confirms this, so it’s a little hard to tell how low levels of activity affect heart health over the long term. Additionally, too much exercise has also been shown to be stressful to the heart. So all this is to say that there’s probably a sweet spot somewhere in the middle for optimal cardiovascular health.
Protein and fat loss go hand in hand. This nutrient supports muscle growth and raises your metabolism, making it easier to slim down. It also promotes satiety and reduces hunger, so you'll eat less without even realizing it. The American Journal of Clinical Nutrition states that high-protein diets can positively impact appetite, cardiometabolic risk factors, body weight and other factors.
