For weight training, you have two options. 1) 3 days of full-body weight training workouts like these, or 2) 4–5 days a week of body part split workouts like this leg workout. If you prefer to train at home, get a set of resistance bands and learn how to use them, along with a yoga mat, and maybe also a pull-up bar and pair of adjustable weight dumbbells.
Be choosy about carbs. You can decide which ones you eat, and how much. Look for those that are low on the glycemic index (for instance, asparagus is lower on the glycemic index than a potato) or lower in carbs per serving than others. Whole grains are better choices than processed items, because processing removes key nutrients such as fiber, iron, and B vitamins. They may be added back, such as in “enriched” bread.
