Regular exercise and intake of supplements are good ways to maintain a healthy body. Most health buffs and health-conscious people are strict on maintaining these two elements in their daily routine. However, the exercise regimen and the consumption of diet supplements of a person would also depend on his motives and his actual health condition. As such, it is no surprise that both diet supplements and exercise are used for different health purposes such as gaining or improving strength, increasing weight, and losing weight.

For gaining weight, the exercise regimen, which would complement a person's diet supplements, can either include aerobic activities or weight-lifting exercises. In exercising to increase weight, it's advisable to focus on less strenuous activities such as lifting of lightweight barbells or jogging, since the exercises are mainly just for toning the muscles and making the body heavier.

Together with the abovementioned exercises, the best diet supplements to be taken when trying to increase weight would be l-Glutamine, creatine, and protein. These supplements help increase the body's energy and lead to an increase in the person's stamina. When observed with a more effective exercise regimen, the intake of these supplements enables the person not to tire easily and to properly do his routines for a longer period of time.

A person intending to shed some weight needs to do more strenuous activities such as swimming, cycling, and brisk walking. In a gym, using a treadmill or a stationary bicycle is one of the most effective ways in shedding pounds. On the other hand, when it comes to the diet supplements, a person intending to lose weight also needs protein, since high protein intake increases the body's metabolism. Among the protein supplements, the most effective protein diet supplement to be taken is whey protein, which contains the highest amount of protein.

Finally, for gaining strength and stamina, a combination of lengthy workout routines and diet supplements is the way to go. People who are after the improvement of their strength could even make use of the various gym equipment in their exercises. For example, lifting heavy weights and exercising with a workout ball make use of the body's underdeveloped muscle areas in the abdomen, shoulders, and legs. In case no workout equipment is available, a person can perform a double set of abdominal crunches, which are just as effective in strength training.

Like in other health purposes, the most effective dietary supplements for strength training or strength improvement are still the protein-based supplements. Protein is particularly useful in body building and strength training activities because it is vital in the creation of muscles in the body; without protein, the growth of muscles would not take place. In particular, the recommended protein diet supplements for those who wish to improve strength are casein, which can be taken before sleeping, and whey, which should be taken after working out. But of the two diet supplements, whey is preferred by many due to its ability to produce protein at a much faster rate.
