Working on Your Workout

(I) Although appreciating a balanced diet and regular exercise, most people do not know how to exercise properly. Consequently, they usually rush through their workouts, or they make the same common workout mistakes. (II) Exercising the right way is important for people who are worried about their health and their appearance. (III) However, if someone is not working out properly, they will not see the results they want. Therefore, training experts have devised tips to teach people how to exercise correctly in order to achieve the greatest health benefits. (VI)

One of the most common workout mistakes is doing the same routine over and over again. This does not challenge your muscles, and it can actually prevent muscles from growing and repairing themselves. Instead of always sticking to the same old workout, it is important to change your routine every six to eight weeks. It is also important to add a variety of workouts to your routine, such as swimming, yoga, or biking, to make sure your whole body stays fit. This will help make your workouts more interesting, and benefit your health and muscle development as well.

Another mistake people tend to make is to work out too hard, too often. Your body needs to rest between workouts; otherwise, no progress will be made. It is best to keep the number of hard workout routines to no more than two per week. Then, for those who don’t want to get off schedule by skipping a day, shorter workouts of about twenty minutes can be used on other days. For more variety in workouts, you could also plan an easier routine for forty to sixty minutes between days of shorter, more intense workouts. Experts recommend, however, taking at least one day off completely each week, especially after several hard workout days in a row.

In reality, no one is perfect. However, if you want to make a difference in your overall health, there are some things you can do. Stretch before and after every workout. Do not rush your routine, and do not work out too little or too much. Remember not to make these common workout mistakes, and always have fun while exercising!

Where in paragraph 1 does the following sentence best fit?

" If you want to achieve the best workout results, here are a few helpful tips to bear in mind.”

Read the following passage about The Elderly in Multicultural Societies: Challenges and Opportunities and mark the letter A, B, C or D on your answer sheet to indicate the best answer to each of the following questions from 23 to 30.

In multicultural societies, elderly individuals face unique challenges and important opportunities. As communities diversify rapidly, traditional support systems are constantly evolving. Seniors often navigate unfamiliar cultural environments while facing significant language barriers that lead to social isolation. These persistent obstacles frequently prevent full access to essential healthcare services or meaningful community participation. Fortunately, innovative local organizations address these critical issues by offering comprehensive translation services and culturally sensitive care options.

Technology presents both remarkable benefits and considerable difficulties for elderly individuals from various cultural backgrounds. Digital tools effectively connect seniors with distant family members globally, yet many older adults struggle substantially with these new communication methods. Recent research shows approximately 65% of elderly immigrants experience digital exclusion compared to native-born seniors. In response, numerous community centers have successfully established specialized technology workshops for older adults from diverse backgrounds, helping them maintain vital connections with overseas relatives and friends.

Cultural differences significantly impact elderly care approaches across communities. In collectivist cultures, elderly family members traditionally live with their children, while Western societies typically emphasize personal independence. This fundamental divergence creates tension when immigrant families attempt to adapt to new societal norms. However, vibrant multicultural environments provide valuable opportunities for exchanging diverse perspectives on aging. Many communities benefit tremendously from adopting hybrid approaches blending traditional cultural practices with modern care techniques, creating more comprehensive support systems.

Economic aspects of aging in multicultural contexts matter significantly for overall wellbeing. Elderly immigrants frequently face severe financial hardships due to limited retirement savings and persistent employment discrimination throughout their lives. Some progressive governments implement supportive policies addressing these vulnerable individuals' unique needs. Certain forward-thinking regions offer specialized employment programs for seniors with diverse cultural backgrounds, recognizing their valuable skills and extensive life experiences. Additionally, creative intergenerational initiatives connecting elderly immigrants with younger community members effectively foster mutual understanding and practical support, successfully transforming demographic challenges into meaningful community enrichment opportunities.

The word “divergence” in paragraph 3 could be best replaced by _________.
