Exercising Tips For Those With Little Free Time
Some people blame their busy schedule for not getting a regular dose of working out. They say they're too tired to hit the gym after attending their jobs. During weekends, they just want to rest or have some quality time with their family. But the truth is you can devote even just a few minutes of your time daily for getting fit.
Of course it may take a while before results show up. Even if you regularly take supplements, you will not see results without working out. There's a reason why supplements are called just that. They're there to complement your working out, and not as a replacement for exercising.
If you only got a few minutes available for working out daily, try to make the most out of it. Keep rests in between routines short. This way, you can perform multiple routines which you can pack in your available free time. Besides, keeping the rate of your heart up throughout will ensure that you burn those calories more effectively.
Wearing a digital sport watch with a stopwatch function will help you stick to your schedule strictly. For instance, you need to stay on the treadmill for 15 minutes only before doing another work out. A stopwatch will ensure that you do not exceed your allotted time on the treadmill. A stopwatch will also be valuable if you need to go to work later on, so as not to be late.
When you get the chance to go to the gym, don't spend a lot of hours in there. Ideally, you should break up the body parts that you work out each time you hit the gym. You can work out the muscles on your upper body one day, then those on your lower body the next. Steer clear of trying to build muscle mass fast. You will only end up exhausted from all the hard work, and still not get results. Or even worse, you might only end up with an injury.
Even if you exercise for only a few minutes regularly, sometimes you end up with muscular pains. This may be a setback, especially if you do your exercising before going to the workplace. You may take over-the-counter pain relievers to help you out. Some of the most commonly used medications are ibuprofen, paracetamol and the likes.
There are also gels and creams which you apply topically for muscular pains. You may also apply compress on the affected area to help hasten healing. Or using an electric massager on the affected muscles will also help provide relief. Before you do your next work out, it's best if no pains are present. You will only fail to work out effectively, plus you're at risk of injuring yourself.
Digital stopwatch circuit diagram which can count 1 millisecond?
is there anyone who can give me a circuit diagram of digital stopwatch which can count 1 millisecond?
any links will also be helpful.
The old 555 timer chip can be fitted with given resistors (R) and capacitors (C) to give you a millisecond pulse width. This depends on the timeconstant Τ
Τ = RC
For example: a 1000Ω resistor and a 1µF capacitor will give a time constant of 1 millisecond and this will result in a pulse width or clocking cycle of 1 millisecond.
