Any health or fitness regime needs repetition and commitment to be effective. A universally beneficial regime that can be easily done at home is yoga. Whether you have a specific health need (aches, pains, mental wellness) or just want to feel better in general, yoga is a good option. If you are a yoga virgin, nothing compares to an in-person lesson with an experienced teacher, but your iPhone or iPad can approximate that experience. Just remember, before starting your practice don’t eat a heavy meal right before (ideally, don’t eat anything or just eat a light meal an hour or so beforehand), pay attention to your breathing, and every pose needs a counterpose.
