Hourglasses were commonly seen in use in churches, homes, and work places to measure sermons, cooking time, and time spent on breaks from labor. Hourglasses were essentially inexpensive, as they required no rare technology to make and their contents were not hard to come by, and as the manufacturing of these instruments became more common, their uses became more practical. As the use of mechanical clocks to indicate the times of events like church services became more common, creating a "need to keep track of time", the demand for time-measuring devices increased.
The hourglass also found popularity on land. Seamen found that the hourglass was able to help them determine longitude, distance east or west from a certain point, with reasonable accuracy. The fact that the hourglass also used granular materials instead of liquids gave it more accurate measurements, as the clepsydra was prone to get condensation inside it during temperature changes. Unlike the clepsydra, the motion of the ship while sailing did not affect the hourglass. Marine sandglasses were very popular on board ships, as they were the most dependable measurement of time while at sea.

In the same period it appears in other records and lists of ships stores. The written records about it were mostly from logbooks of European ships. Use of the marine sandglass has been recorded since the 14th century. But it was not until the 14th century that the hourglass was seen commonly, the earliest firm evidence being a depiction in the 1338 fresco Allegory of Good Government by Ambrogio Lorenzetti. There are no records of the hourglass existing in Europe prior to the Early Middle Ages the first documented example dates from the 8th century CE, crafted by a Frankish monk named Liutprand who served at the cathedral in Chartres, France.

It had gotten to the point where I began to dislike Alexa’s voice, because I associated it with those gritty wall sits. The soft alarm sound at the end of that minute was a lifeline, but it felt like it took forever to get there. Every time I hear Alexa’s dulcet tones say “okay, one minute, starting now,” I find myself gritting my teeth in anticipation of the tough time ahead of me. For an added benefit, make sure you’re looking straight ahead, put your hands behind your head or extend them out in front of you, suck in your stomach slightly and tense your abdominal muscles.

Once you get into this position, it’s quite fiddly to play with your phone and get the timer set up, so I just used the Amazon Echo Dot in my living room to ask Alexa to set a one-minute timer. If you’ve never tried this before, or are very new to strength training, 15-30 seconds might be an achievable goal for you. Now, here’s the tricky bit: you have to hold the position for a specific amount of time.
