Is vigorous, high intensity exercise or prolonged, intense sexual activity safe if you're prehypertensive but otherwise healthy?

Is vigorous, high intensity exercise or prolonged, intense sexual activity safe if you're prehypertensive but otherwise healthy?

Start slowly: If you haven't been very active prior, ease yourself into exercise. High-intensity interval training can be great but also predispose you to injury if you don't have some fitness base. Otherwise, if you have no other issue, prehypertension isn't particularly concerning and exercise, including sexual activity, is good for you. Listen to your body though, and consider touching base with your doctor ...Read more

Is a 30 min walk as good as a vigorous 15 min bike ride with high intensity intervals? I'd like to find the quickest and easiest form of exercise.

Either: Training is used for multiple purposes. While many exercise experts and trainers advocate high intensity short interval training with frequent variation to improve strength and endurance, walking for cardiac aerobic training often aims to push the heart rate to a certain aerobic target (65-80% of maximum predicted hr = 220-age). Depends on your goals therefore. Always try to push the envelope. ...Read more

Is 100grams of carbs enough for a high intensity boxing workout? My weight is 75kg

Is 100grams of carbs enough for a high intensity boxing workout? My weight is 75kg

Might be.: You gut can only absorb about 45 grams of carbs every hour, no matter how intense your workout. So if your work out is in the 2 hours range, that should be enough. If you are working out less, then it's likely too much. What's more important is the post workout snack. You will need about 120-150 kcals within about 1 hour of finishing. This helps restore your energy stores for your next workout. ...Read more
