[推運動] 8 Reasons Why Your Workout Isn't Working

8 Reasons Why Your Workout Isn't Working

Sneaky Reasons Why You're Not Getting Results
  -- By Jennipher Walters, Certified Personal Trainer and Fitness Instructor
We all know how fantastic working out is for your health. But what happens when your workouts aren't delivering the results you want? Or you're not getting the results you think you should be getting? While any kind of physical activity is good, some workout plans are better than others and—as you might suspect—a lot of other factors come into play when trying to lose weight and tone up. So if your workout isn't working for you, one of the following eight reasons could be to blame. Find out how to turn that around and get the results you deserve!

1. You're not working hard enough.
If you have been exercising consistently for several weeks, months or years, it's definitely time to increase the intensity and start pushing yourself. As you work out more and more, your body adapts and becomes more efficient at doing that certain activity. This means that over time, the 30-minute workout that was challenging for you three months ago doesn't provide the same results. In fact, you're actually burning fewer calories and your body is no longer changing if you're still doing the same old thing.
Get-Results Remedy: In order to get results from exercise, you have to regularly push yourself beyond your fitness comfort zone. Whether you increase the frequency, intensity, or duration of your workouts, you have to switch it up. Not sure where to start? Try adding an extra day of cardio onto your routine, testing out a new group exercise class at the gym, adding another loop around your walking track, or bumping up the incline and speed on the treadmill. Remember, when it comes to exercise, change is good—and that change should be challenging!
2. You're working too hard. 
Yes, you can actually work out too hard and too much. If you're someone who goes all out in every workout, or rarely to never takes a day off to rest, you could actually be breaking your muscles down instead of building them. If you always feel tired and sore, have unexplained headaches, insomnia or just a general lack of motivation and an inability to complete your workouts, you may be overtraining.
Get-Results Remedy: Take three to five days off of exercise altogether. It may be hard for you to do this, but know that you must allow your body the time it needs to rest and recover. Get plenty of sleep each night and fill up on nutritious foods. Then slowly ease back into your routine, making shorter, less intense workouts part of your workout plan. And remember to always take one to two rest or easy active recovery days a week!
3. You haven't changed your diet. 
Exercise is awesome, but if you're not eating a nutritious diet with the appropriate number of calories for weight management, you could be shooting yourself in the foot. Proper nutrition fuels your workouts, but eat too much and you could gain weight (or hurt your weight-loss efforts), and eat too little, and you won't have enough energy to exercise.
Get-Results Remedy: If you can't seem to see those muscles you're trying to build, startlogging your foods to see how many calories you're eating a day. If you're regularly eating more than you should (it just takes an extra 100 calories a day to gain an extra pound a month), then try choosing lower-calorie versions of your favorite foods and slowly decreasing your caloric intake until you're at the right level! On the flip side of that, if you find that you're eating too few calories, that can also slow your metabolism and leave you drained at the gym. Find out how many calories you need to manage your weight by visiting your SparkPeople Nutrition Tracker.
4. You're only doing cardio. Yes, cardio is important for calorie burning, but a proper exercise plan includes cardio, strength training and flexibility. If you're just doing cardio, then you will be burning calories and strengthening your cardiovascular system, but you won't be really changing your body composition by building more muscle. For that you need strength training!
Get-Results Remedy: Lift weights or do body-weight exercises, such as lunges and push-ups, at least twice a week to reap the amazing benefits of resistance training; including decreased body fat, increased muscle mass and stronger bone density. For hardcore cardio fans, you can also try kettlebell training or circuit training, which is like getting a strength and cardio workout at the same time!
5. You reward yourself with food.
Do you allow yourself to have that extra piece of pizza or order that dessert when dining out because you "went to the gym" earlier? If so, you may be undoing all of that good calorie-burning with too many treats.
Get-Results Remedy: Familiarize yourself with the calorie contents of your favorite foods—and find out how many calories you're really burning through exercise. (SparkPeople's Nutrition Tracker and Fitness Tracker will help you learn!) Remember that while you may have run 3 miles at the gym, that only burned 300 calories, which isn't nearly equivalent to the calorie count in that brownie sundae you ate later. Focus on how good exercise makes you feel rather than what it allows you to eat after; and choosefoods that fuel your workouts, rather than the other way around.
6. You're doing too much too soon.
Unfortunately, results don't happen overnight. It takes time and consistency to get in shape over the long haul. But how many of us decide that we're going to get in shape and then get totally gung-ho, spending hours at the gym only to find ourselves tired, sore and no thinner after a week or two?
Get-Results Remedy: Be patient. Remember that you're creating a lifestyle change that you can sustain for the rest of your life. While there's temptation to start off doing extra long and hard workouts, don't. Build up to doing those tough workouts gradually as the weeks go by. Not only will this prevent injury and give your body more time to adapt and change, it will also give your life and habits time to change—permanently!
7. You're trading sleep for workouts. 
We're all so busy these days, and sometimes the only time to work out seems to be early in the morning—even if you were up late the night before working or with a child that couldn't sleep. But regularly swapping sleep for workouts can seriously hinder your weight-loss, as sleep triggers a number of hormones that influence cravings and a tendency for weight gain. In addition, too many sleepless nights will leave you tired and unfocused for your workouts, which means that you won't get much from your efforts. And did you know that sleep is a much needed part of a fitness plan, since a lot of recovery and repair happens while you rest each night? Skimp on the shut-eye, and it could also lead to symptoms of overtraining.
Get-Results Remedy: Start scheduling both your sleep and your workouts—and treat both as unbreakable appointments. Then follow SparkPeople's 4-week Better Sleep Challenge to make the most of those Z's! Exercising after an occasional sleepless night shouldn't pose too many problems. But if you're regularly swapping sleep for a sweat session, you could be doing more long-term harm than good. Sleep should come first—even before working out.
8. You sit all day. 
Sure, you work out regularly, but what you do the rest of the day matters, too! If you put in a solid exercise session only to sit at a desk all day and lounge in a recliner watching TV at night, you may be undoing all of your hard work at the gym. Plus, there are a number of new studies that say too much sitting can be bad for our health and our waistlines—even if you exercise during the day.
Get-Results Remedy: Try to work more activity into all areas of your life by going for a walk after dinner, choosing to stand whenever possible, taking the stairs, parking your car further away and replacing your TV time for more active relaxation (like playing with your dog). Also, if your job requires you to sit in front of a computer all day, set a timer to beep every half hour or hour to remind you to stand up, stretch and do a quick lap around the office.

If you're not seeing the results you want, you may be guilty of more than one of the mistakes above. Follow these tips to feel better, have more energy and get the workout results you want and deserve!

運動塑身無效的八個原因

1, 運動的不夠
如果你已經規律的運動一段時間(數週,數月,甚至數年),那肯定要增加運動的強度,並開始對自己施壓。當你訓鍊的越來越多,你的身體就開始適應,變的對做那項運動越來越有效率。三個月前做30分鐘的訓鍊對你來說是個挑戰,但是現在做同樣的事不會有一樣的結果。事實上,如果你一直做同樣強度的鍛鍊,你會燃燒比之前較少的熱量,而且身體不會有所改變。

措施: 為了得到成果,你必須定期的強迫自己超出訓鍊的舒適圈。不論是增加運動的頻率,強度,或是持續的時間,就是要有所突破。試著這樣開始: 增加一天做有氧運動,或參加新的健身房訓練課程,增加一段散步路程,或是增加跑步機的速度或坡度。只要開始運動,任何挑戰都是好的。

2, 運動的太多
當然你可以讓自己訓練的十分艱苦吃重。假如你是個每天做各種訓練的狂人,或是很少找一天來休息,你很可能會傷害你的肌肉。如果你總是感到痠痛疲勞,莫名的頭痛,失眠,訓練時力不從心,你很可能就是訓練過度了。

措施: 一週運動3~5天。也許對你來說很困難,但總是要讓身體休息復原。睡飽一點,吃營養的食物。稍微減少運動的份量,慢慢回到規律的訓練,記得一週至少要有1~2天的休息日。

3, 沒有改變你的飲食
運動超棒! 但是如果你沒有針對你的體重管理來吃營養的食物並攝取適當熱量,你就會被食物打敗。適當的營養是訓練的燃料。吃太多可能減緩減重效果或是增胖,吃太少會沒有足夠的能量來運動。

措施: 假如你要鍛鍊的肌肉沒有變大,開始記錄你每天攝取的食物和熱量。每天多吃進100卡的熱量,一個月就會多0.45公斤。假如吃太少,就會降低新陳代謝且運動時筋疲力盡。

4, 只做有氧運動
有氧運動對燃燒熱量很有幫助,但是一個適當的訓練計畫應該包含有氧運動,肌力訓練和伸展拉筋。如果只做有氧運動,會燃燒熱量,強化心血管系統,但是你的身體組織無法透過肌肉的增加獲得改變。所以你需要肌力訓練。

措施: 做重量訓練,或是身體重量阻力訓練,例如仰臥起坐/伏地挺身,一週至少做兩次。阻力訓練有如下效果: 降低體脂肪,增加肌肉量,增加骨質密度。有氧運動的狂熱者,可以試試壺鈴訓練或是循環訓練,這可以強化肌肉並同時做有氧運動。

5, 用美食獎賞自己
訓練完後,你是否會因此讓自己多吃一塊比薩,或是多點一份甜點?這會毀了你之前的努力。

措施: 熟悉你愛吃的食物熱量是多少,並了解你透過運動燃燒多少熱量。好不容易運動燃燒了300卡,可不等於運動後可以吃一個布朗尼蛋糕冰淇淋。記得運動帶來的好處,並且吃對訓練有幫助的食物。

6, 你做的太多太快
訓練成果需要持續一段時間才看的到,效果不會立即顯現。但有多少人決定運動減肥後,卯起來在健身房待好幾個小時,搞得自己又累又痠痛,但過了一兩個禮拜卻完全沒變瘦?

措施: 耐心點! 記得你是在創造一個可以和你共度餘生的生活方式。有時會想去做那種狠操的訓鍊,別這麼做,應該要花幾個禮拜慢慢加強到那種強度,不但能避免傷害,讓身體多點時間適應轉換,還能讓你的生活習慣永久改變。

7, 你犧牲睡眠來運動
有些人很忙,為了運動,即使前一天很晚睡,依然早起做運動。但通常犧牲睡眠時間來運動會阻礙減肥,因為身體有一連串的活動需要在睡眠時進行。此外,睡眠不足會讓人疲勞,而且無法專心在訓練上,造成訓練效果不佳。睡眠是訓練計畫中重要的一環,很多的復原和成長都在每天的睡眠中進行。睡眠不足可能導致和訓練過度類似的結果。

措施:把睡眠和運動都排進行程,而且嚴格執行。偶爾一天沒睡飽不會影響訓練,但如果你總是犧牲睡眠時間來運動,長期下來得到的傷害比好處多。睡好覺是第一要務,甚至比運動還重要。

8, 你坐了一整天
(不翻了...就是建議你不要除了運動時間外都坐著,如果是電腦上班族,也固定時間起來活動一下,晚餐後也建議散個步之類的)

[推健康] 抗性澱粉可以燃燒脂肪

在許多人的減肥大計裡,澱粉永遠是大敵,幾乎每個減過肥的人都曾經和街上美味的雞蛋糕、豬血糕、蔥油餅、炸醬麵…奮戰過。

但最新研究發現,非但不需如此,更且,澱粉類應該加入你的減肥計劃。

▲為什麼?發表在《營養與代謝》期刊的研究指出,多吃含抗性澱粉的食物,因為能降低脂肪儲存而減下體重。只要你將每天所吃的澱粉類,將其中的5~6%用抗性澱粉取代,就能達到減重效果。

▲抗性澱粉是什麼?長久以來膳食纖維分為水溶性纖維和非水溶性纖維,但近20年來,科學界一直在研究第三類纖維─抗性纖維,被認為是近年來碳水化合物和健康關係中一項重要成果。

一般人每1克抗性澱粉平均提供2.8卡熱量,對於血中胰島素偏高的人,每公克抗性澱粉則僅2.2卡,仍低於一般澱粉每克提供4卡的熱量。

通常吃下澱粉類後,會產生燃燒熱量,但抗性澱粉無法消化或吸收,只好讓脂肪排上首位先行燃燒。和其他纖維一樣,可以提供飽足感,飽腹作用較為持久。

▲抗性澱粉分成四類,前三類在日常飲食中十分常見:
  • 第一類存在於種子類、豆類、全穀類等未加工的食物。
  • 第二類指類生的、無法完全糊化的物質,如生的馬鈴薯、生香蕉等。
  • 第三類指的是烹煮過又冷卻的老化澱粉,如隔夜飯。
  • 第四類則是在實驗室裡將第三類的老化澱粉純化後變成粉末,可以直接加在纖維較少的優格或牛奶裡,因此此類抗性澱粉也將成為食品加工業未來的明星。

抗性澱粉的建議攝取量至今沒有定論,但美國民眾每日飲食中抗性澱粉約攝取3~8克,中國大陸則為18克,為了獲得腸道相關的健康效益,建議每天攝取20克抗性澱粉。

抗性澱粉不只是減重新武器,還有更多健康益處。

抗性澱粉無法被小腸消化吸收,而直接旅行到大腸,為腸道內益生菌發酵過程提供養分。因此研究指出,將已經罹患結腸直腸癌的病人臨床介入發現,每天給予30克的抗性澱粉,結腸息肉有絲分裂(細胞分裂週期的一部份)的比率明顯低於沒有吃抗性澱粉的人。

而且,因為抗性澱粉無法消化的特性,有利於血糖控制。中國大陸的研究發現將第二型糖尿病人隨機分組,一組每天給予30克的抗性澱粉,另一組不攝取抗性澱粉,結果顯示吃抗性澱粉組的飯前、飯後血糖都明顯下降。

根據抗性澱粉的原理,馬偕醫院營養師趙強有以下建議:

1.主食多選擇含抗性澱粉的食物
例如早餐挑選燕麥粥便是就是終極好早餐。一碗煮好的燕麥粥就有0.7克的抗性澱粉,若將香蕉切片撒上,又可以增加4.7克的抗性澱粉。

馬鈴薯若不油炸變成薯條,就是澱粉模範生。1顆煮熟的馬鈴薯有3.2克的抗性澱粉,而且熱量才300卡。和馬鈴薯同一家族的地瓜也有3克的抗性澱粉。

2.吃米飯變成很有學問

為了吃到更多的抗性澱粉,首先可以做的是將主食從白米、白麵條、白麵包,改成糙米、全麥麵條、全麥麵包。煮好半碗的白飯抗性澱粉含量是0.6克,糙米卻是3克。

壽司因為是冷飯,加上醋可以控制血糖,成為減重好幫手。最重要的是因為白飯放冷後,抗性澱粉又會回升,達到0.95克。

隔夜飯也大翻身,雖然隔夜飯在冰箱裡儲存後回溫加熱,抗性澱粉又再次減損,但依舊比原本的熱飯高,所以推薦吃剩飯,不要浪費食物,也節能環保。

減肥時,烤飯糰應該被打入冷宮。因為米飯烤了之後,澱粉分子變小,抗性澱粉又降低,所以應該少吃。

3.生的比熟的好,脆的比爛的好

澱粉類裡不能糊化的物質如馬鈴薯、青香蕉裡都有豐富的抗性澱粉。以山藥為例,日本料理裡生的磨山藥就比台式料理的山藥排骨,有更多的抗性澱粉;中國大陸的家常菜脆溜「土豆(馬鈴薯)」的抗性澱粉,就比馬鈴薯泥來得多。

飲食中多選擇富含抗性澱粉的天然食物,包括全穀類、豆類、部份蔬菜水果,讓飲食生活更加健康,也可以得到抗性澱粉帶來的減重好處,不過不管哪種澱粉、哪種纖維,仍然不是減重真正萬靈丹,最終還是要回歸健康的生活習慣。

【10種抗性澱粉排行榜(單位/抗性澱粉含量[克])】
  • 香蕉/中等1條/4.7
  • 地瓜/1顆約5公分大小/4.0
  • 馬鈴薯/1個(水煮、冷的)/3.2
  • 糙米/半杯(煮過)/3.0
  • 玉米/半杯/2.0
  • 義大利麵/1杯、冷的/ 1.9
  • 豌豆 /半杯,煮過/1.6
  • 黑豆 /半杯,煮過/1.5
  • 燕麥 /1杯(煮過)/0.7
  • 全麥麵包/2片/0.5

小洋-夏日南國2日遊-20110702-0703

高雄行DAY01-高鐵初體驗,嗯,真的是相當便利的交通方式。
這次回高雄主要就是回中山參加GF20週年慶。
中午先跟我們這屆夥伴聚餐(呈呈很可愛),
下午參加學弟妹熱情舉辦的社慶,跟許多夥伴十幾年沒見囉,
欣賞學弟妹很棒的表演,透過拍照大地遊戲跑一趟社辦跟集訓場地,
感謝讓我們再次有機會聚在一起,也勾起大學時代的回憶。

傍晚從渡船頭晃到駁二特區,體驗高雄的新氣象。
晚上CHECKIN 高雄福容飯店(多虧公司福委會簽特約)。
八點半再次到MO JAVA用餐,真是值得大推的餐廳。
FISH CAKE GREAT!!

餐後沿著港邊的單車步道散步回飯店,
What a wonderful day! PS: 高雄天氣真的好到爆炸,
光是在文化中心走路等人,就快曬成人乾。ORZ

高雄行DAY02-五點半被窗外的港邊陽光曬醒,
梳洗後整理了一下以前社團照片,
嗯,真的有很多有趣的回憶(還有金門隊的哩),
六點半跑到飯店健身房慢跑40分鐘跟重訓(隨時保持運動好習慣很重要喔!)。

下午再次跑到駁二特區,讓我印象深刻的是勞工博物館這次的主題-吉他。
除了形形色色的吉他,也看到高雄YAMAHA在2007關廠後的回憶錄,
很令人感動。由於背著將近10KG的東西在大熱天下"鍛鍊身體",
只好早早搭捷運回到左營。女王突發奇想嚐嚐劉家酸菜白肉鍋!!
兩個人便殺到海軍中正堂,下午兩點以後火鍋半價喔!!
兩人套餐應該要四個人吃(所以打包了...ORZ) 口味相當好。
再次回到左營站後,在彩虹市集晃了好久。
台灣對於個人創作市場接受度越來越高,很好的改變呢。
特別的是在這找到了一枚跟我"有緣"的銀戒。YES!!

高雄行番外篇-今天搭高鐵回台北時,
巧遇來台演講永不放棄的力克‧胡哲在工作人員協助下,
從身邊經過(有多近呢~就坐在旁邊一樣)。
看見他面帶笑容,雖然僅僅幾秒鐘,
當下的感染力已經讓我知道熱愛生命就應該如此!!
