What causes your muscles to burn after a workout?
Lactic acid accumulation has been assumed to be the cause of muscle burn for many years. In the past few years, it has been discovered that lactic acid is not a by-product but is actually a source of fuel for muscles. So very little accumulates in the cells and greater lactic acid presence helps endurance, by providing needed fuel. Lactic acid will disappear within an hour of exercising, and is no longer thought to be responsible for muscle soreness that may appear 1-3 days after exercising.
Current thinking holds that calcium is the primary culprit for muscle soreness. Muscles contract through neuronal activation of calcium channels, which in turn cause the activation of contractile proteins. However, after continued activation, calcium channels become leaky. The muscles fatigue due to running out of the calcium supply to keep them contracting. As for the burn itself, it is not entirely clear. Some researchers hold that the same leaky calcium channels are also responsible for muscle burn, but it may just as well be other substrates within the muscle cells that are responsible.

Press ups help biceps, lats, stomach, and triceps I personally think that press ups work more then push ups and I am a strengthening coach for a high school
well first you have to have a certain amount of body fat, 10% I think. Once you attain that you would need to first build up some cardio to endure the hard physical work of getting abs. Once you have finished that step you would constantly need to do crunches, sit-ups, and all the other abdominal workouts. you would also need to watch what you eat, and maintain a healthy lifestyle. GOOD LUCK!!!!!!!!!!!!!!
What can cause dizziness brought on by heat and or exercise?
Dizziness brought on by heat or exercise can be caused by dehydration and/or low blood sugar.
(Since this was originally put in the Migraine category, I will also answer that both dehydration as well as low blood sugar can trigger migraines, and migraines can cause dizziness. Also, there is something known as Exercise Induced Headache, whereby just by doing exercise can trigger an intense headache. Dizziness may be a part of that headache as well.)

Hour long is too long to work out?
Depends entirely on what you are after, muscle endurance? or muscle strength. If you want muscle endurance i recomend a longer workout, about 2-4 hours 3 times a week. How you do this is you take a light weight. say you have a 45 lb bench press bar. your max is 200 (max weight you can bench at least 1 rep.) you would stick 2x 35 lb weights on. do this like a normal bench press. but SLOW slowly resist down to ur chest. as soon as it hits your chest. pop it. push it up fast. that will shock train your muscles, extending endurance. if you want muscle strength, you will workout for about 1-2.5 hours 4-5 times a week, try to prevent doing the same exercise to days in a rown, it will weaken ur muscles. if you are looking to look toned and ripped, then run, run forest run. it tones your muscles, making them more defined.

What exercises can you do on a big exercise ball?
The ball is a great way to add instability to your workouts, increasing difficulty, and allowing your body to work as a whole. Any routine that utilizes your body weight is best. Some ideas include:
- Superman on the ball
- Hamstring Curls
- Planks
- Squats
- Push ups
To maximize the effectiveness, I recommend engaging your core at the same time and really focusing on form. Doing sit ups on the ball is a common exercise but I do not recommend this. Most people, if not all, do sit ups in a flexion motion. With flexion you add increased pressure on your spine, which is one of the leading causes for lower back pain.
