Are you tired of being out of shape? Do you want to get back into the shape you were in when you were a teenager (or at least your twenties)? We have some pieces of advice that can help you accomplish these goals. Follow this advice, and you will be on your way.
When you are weight lifting to increase fitness, it is always preferable to use free weights, not machines. This is because the free weights will allow you to build up the supporting muscles around the major muscle groups. Machines, instead, focus on very specific areas. You will see an increase in the amount of weight you can lift on the machine, but not as much strength as if you used free weights.
