1. Convenience Counts
Free weights take up less space than fitness machines, and a set of free weights lasts longer than a machine since they're virtually indestructible. Free weights allow great flexibility in customizing a weightlifting routine. You can use the same set of dumbbells and barbells to train all the major muscle groups. Free weights are also a great option while you're on the road. Business travelers often have access to free weights in hotel fitness facilities.
2. The Pros Outweigh the Cons
Free weights have many advantages. Resistance training using free weights helps build bone density and reduce the risk of osteoporosis. There is also evidence that free weight exercises reduce the risk of type II diabetes. In addition, free weight exercises increase your metabolism, which is critical for weight loss. You'll burn more calories while at rest if you have more muscle mass.
3. Free Weights Aren't Free, but They're Economical
Buying free weights is much easier on the wallet than fitness machines. The cost of a barbell set and weights is surprisingly affordable, especially compared to larger fitness machines. Many large sports equipment retailers carry barbells and dumbbells. Fitness machines are expensive, and you usually need multiple machines to cover several muscle groups.
4. Barbells Explained
There are 2 types of barbells: standard and Olympic style barbells. The types of weight for each barbell are not interchangeable. The difference is the size of the barbell that holds the weights. Olympic weights have a larger hole cut out of the middle to fit the Olympic style bar. The Olympic style bar provides more freedom of movement because the outsides of the bar will spin and provide less strain on the wrists. If you are on a budget, you might find a used free weight set at a local yard sale. There are really no safety concerns with buying used barbells and dumbbells.
5. Spotting is Good
If you plan to lift heavy weights, you should have a spotter in case the weight becomes too heavy in lifting. Use a spotter whenever you're performing heavy bench pressing. The spotter can grab the weight or assist with the lift whenever it becomes too heavy. There are other lifts where a spotter is handy, but not a total necessity; a good example is barbell curls.
