The short answer is no.
However, it depends on your goals. Are you looking to become a bodybuilder and compete on stage one day? Then you don’t only need a gym membership, you need a personal trainer that has experience in training athletes to achieve these goals.
If you’re like most of us who are just looking to stay fit, look good and feel amazing, then you can get great results working out at home with minimal equipment. The key to anything is consistency. What is the best cardio? The one you’ll do everyday! If a 30 minute brisk walk every day is all you can commit to, start there.
There are no short cuts and exercise is less than 20% of the equation, a healthy diet makes up the rest. The saying that “abs are made in the kitchen” is 1000% true.
