[Q]: When I first heard about the 7-Minute Workout  an app that promises the benefits of a sweaty bike ride and a trip to the gym in just a few minutes  I thought it was all hype. But as it turns out  the app  well  works you out. I tried it for the first time last year  and I'm still hooked  so I recently got in touch with  Chris Jordan   the director of exercise physiology at the Johnson & Johnson Human Performance Institute and the person behind the Johnson & Johnson Official 7 Minute Workout  to get some insight into how it works. For me  the app is perfect for weekends  or when I can't make it to a yoga class  or as something fun to do with a friend at home. View As: One Page Slides
It consists of 72 exercises like jumping jacks  sit-ups  and push-ups. Ten require nothing but your body  and for others  you'll need a chair that can support your weight. The latest version of the app lets you do each exercise along with  Jordan .
The idea of a workout you can do in minutes was originally envisioned by  Jordan   an exercise physiologist. Here is personal trainer and study partner  Brett Klika  demonstrating one of the workouts. Sources: American College of Sports Medicine's Health & Fitness Journal  YouTube
The concept behind the workout is interval training â short  intense periods of exercise broken up by brief periods of rest.  Jordan  told me  he  based the workout on  his  experience as a fitness consultant for the US Air Force in Europe.

The approach is less time-consuming than a traditional workout  but studies suggest it may be more beneficial for building muscle and protecting the heart. "High-intensity interval training can provide similar or greater benefits in less time than traditional longer  moderate-intensity workouts  " Jordan  said.

[Q]: Undersheriff Kevin McMahill of the Las Vegas Metropolitan Police Department  said at a press briefing the department has been exploring every aspect of Paddock's life  from birth to death  in search of an explanation.  He  said they have looked into details regarding Paddock's personal life  political affiliations  social behaviors  and economic situation â but answers remain evasive.
"We have been down each and every single one of these paths trying to determine why. Trying to determine who else may have known of these plans  " McMahill  said  adding that the rumors and speculation that have abounded in the wake of the shooting have been unhelpful to their investigation.
"In the past  terror attacks or mass-murder incidents  motive was made very clear  very clear in most of those cases by a note that was left  by a social media post  by a telephone call that was made  by investigators mining computer data  " McMahill  said. "Today in our investigation  we don't have any of that uncovered. I wish we did. We will and are continuing to investigate with great tenacity and hope to arrive at an answer."
 McMahill  also shot down several prevalent rumors that have circulated throughout media reports  telling reporters that they are confident no second shooter was in the room with Paddock during the attack.  He  said  he  could not  however  confirm whether any other people knew about Paddock's plans to carry out the shooting.
 McMahill  also said investigators do not believe anyone other than Paddock accessed  his  suite before the attack  despite reports suggesting a room key was used to enter  his  suite while Paddock's car was outside the hotel's parking garage.
 He  also said the Tannerite â an explosive powder used for long-range target practice â that was recovered from Paddock's home was not in a condition to be used in an IED  as others had questioned.  McMahill  said  it  was also unclear what Paddock intended to do with the tannerite.
Investigators are  however  "keenly interested" in Paddock's medical status at the time of the shooting   McMahill  said. The Las Vegas Review-Journal recently reported that Paddock had been prescribed the anti-anxiety drug diazepam â also known by its brand name  Valium.
"It's really imperative that the listening public have a very clear understanding that there are still a number of people out there that know that something looked out of place  " McMahill  said. "Someone may have been acting suspiciously that night  or in the years prior  the months prior. Somebody that may have seen something or know something."

[Q]: The Senate passed a sweeping bipartisan spending bill Friday morning  but not before the federal government shut down when Sen. Rand Paul (R-Ky.) delayed the vote past midnight to complain about the budget deficit. It was the second government shutdown in less than three weeks.
Sen. Rand Paul (R-Ky.) on Feb. 8 spoke on the Senate floor against a bipartisan budget deal and delayed a vote on the measure. (U.S. Senate)
Then  as an expected vote approached in the Senate   Paul  began to throw up roadblocks  demanding a vote on  his  amendment that would demonstrate how the two-year budget deal breaks past pledges to rein in federal spending.
GOP leaders refused to allow  him  to offer the amendment  arguing that if  Paul  got an amendment vote  many other senators might want one  too.  Paul   in turn  refused to allow the vote to go forward  making use of Senate rules that allow individual senators to slow down proceedings that require the consent of all.
“I can’t in all good honesty  in all good faith  just look the other way because my party is now complicit in the deficits ”  Paul  said on the Senate floor as evening pushed into night.
 Paul  objected after a visibly irritated McConnell tried to move to a vote. Then  Paul  launched into a lengthy floor speech deriding bipartisan complicity on deficit spending while the country goes “on and on and on  finding new wars to fight that make no sense.” The senator direly predicted a “day of reckoning ” possibly in the form of the collapse of the stock market.
As the hours ticked on   Paul  repeatedly refused to consent to allowing the vote to happen  as lawmakers and aides of both parties grew increasingly annoyed at  him . Sen. John Cornyn (R-Tex.)  leaving the floor after an unsuccessful attempt to curtail  Paul ’s standoff  called the gambit “grossly irresponsible” and said that leaders would not entertain  his  demand for a vote.
Senators of both parties were left fuming  with most of their ire directed toward  Paul .
“ He  has mastered the art of ticking off  his  colleagues ” said Sen. Christopher A. Coons (D-Del.).
“It’s a colossal waste of everybody’s time ” said Sen. John Thune (R-S.D.). Of  Paul   Thune said  “He never gets a result.”
 Paul himself  made no apologies as  he  delivered one floor speech after another  casting  himself  as a lone defender of fiscal austerity  despite having voted in December for a tax bill that added at least $1 trillion to the debt.
