What is better a machine or free weights? Machines are usually easy to learn and relatively safe, and unlike free weights machines provide resistance for the entire range of motion, while using free weights there are many exercises with natural resting points where gravity no longer creates adequate resistance. Machines also allow you to go heavier without a spotter, but another disadvantage is not engaging the smaller stabilizer muscles, allowing the primary muscles to grow disproportionately stronger, which can lead to muscles strains or tears. Free weights are superior when it comes to variety of exercises and angles, not locking you into a single plain like most machines. Having that variety allows you to more options in your training routine to keep your muscles guessing and growing. Both machines and free weights have their advantages and disadvantages; make sure to incorporate both in your training program.
