eat for flexibility

Whilst you’re at home, you can help to maintain your flexibility through the food you consume.
Staying hydrated is essential to remaining supple and flexible, helping lubricate joints and delivering essential nutrients to your body. As well as drinking lots of water, eat loads of water dense foods such as cucumber, tomatoes, spinach, lettuce, mushrooms, melon, strawberries, broccoli, brussel sprouts, oranges, apples, blueberries, broths and soups, zucchini, celery, yogurt, bell peppers, cauliflower, cabbage, grapefruit and coconut water. 
Try to limit caffeine intake to 100mgs per day. Caffeine dehydrates you and makes you feel stiff in your joints and tissue.
Magnesium rich goods like green vegetables, especially kale and spinach, nuts and seeds and dark chocolate (85%+) help relax muscles, lessen chronic pain, migraines, stress and anxiety and boost energy.
Sulphur rich foods – cruciferous vegetables broccoli and cauliflower - are important for the health of connective tissues
Foods high in Vitamin C, (kiwis, berries, and broccoli) can help the production of collagen and other components that build youthful elastic muscles and connective tissue 
Inflammatory foods, sugar, processed carbs, and unhealthy fats can create stiffness and bloating.  Increase consumption of anti-inflammatory foods - fish high in Omega 3 fatty acids like salmon, mackerel, tuna, and sardines, ginger, turmeric, pineapple, green leafy vegetables, nuts and seeds and berries 
Don’t eat too much protein as excess protein can dehydrate you and make you feel stiff
Avoid toxins like MSG (my body aches after I eat it!)
Try to have a 12-16 hour fast daily – have atleast a 12 hour break between dinner and breakfast
You might also like to consider the following supplements:

•  Magnesium 400-800g before bed
•  B12 and B complex 
•  Omega 3’s triglyceride form, CO2 extracted fish oil or EPA/DHA algae oil 2-3 grams/ day
•  Vitamin D 
•  Sulphur methyl sulfonyl methane MSM 1-2 grams per day
•  Vitamin C helps your body produce collagen which aids the elasticity of your tendons, muscles and ligaments, 
•  Collagen 

There's so much you can do to improve your flexibility simply by making good choices (and a little stretching too!)
