You must always lift your weights with focusing on the movement. Try not to perform the movement too quick and also focus on the muscle you are working. If you find yourself having to swing to bring the weight up, it’s probably too heavy for you. On certain movements you should be able to cheat a little bit to move the weight. However, you should discuss work with a personal trainer on these types of movements.
I understand that a model/celebrity’s image is their livelihood, but what message does this send to girls growing up in this day and age? I try to make comments about Photoshop to my daughter as she reads Teen Vogue, and i think in the back of her mind she is aware that the images she’s looking at are not reality. However, in her everyday life, she tries to emulate “perfection,” and when she falls short (which we all do), she can get very upset, either with herself or with the product that she has saved up for weeks to buy (they are not cheap).
