I'm always, always jabbering on about how if you want to get better at the things you're not so great at, then you have to work on them.  But how exactly do you do that?  With this workout, that's how!

"Death By … " Workout

Affectionately named "Death By …" at The Fit Pit, you basically pick a movement that you want to work on and then do it, until you can't do it any more — following the pattern of doing a rep at the top of every minute (starting with 1 rep at 0:00) and then adding another rep as the top of the minutes tick by.  So …

0:00: 1 rep
1:00: 2 reps
2:00: 3 reps
3:00: 4 reps
4:00: 5 reps
And on and on …

Get the gist?  (An easy tip to keep track of your rounds/reps:  you're always one rep behind the minute count.)  It starts out pretty easy because with the lower rep counts you have more time to rest.  And then, by about the time you get to 7 minutes or so, it gets a little crazy.

You can basically do any movement you want to get better at, but here are a few suggestions:

• Burpees
• Box jumps
• Push-ups
• Push presses
• Pull-ups

I did the workout twice — once with burpees and then once with box jumps because I want to get better and faster at both of them.  I'm happy to say I got through 10 rounds of burpees (which adds up to 55 burpees!) and 15 rounds of box jumps (which adds up to 120 total box jumps!).  For 25 minutes total of exercise, it was QUITE the workout.  Try it!

If you detest cardio and would much rather be lifting weights (or doing just about anything else, for that matter), you'll totally adore these Instagram quotes.

It's hard to hold anything for one minute, let alone see results.  We get that.  However, we're going to tell you how you can build up to holding a pretty tough exercise for 60 seconds, and results will follow.  The magic move you're going to love to hate is a variation on the oblique V-crunch.

The Oblique V-Crunch Hold

This exercise is super effective for carving out your abs and waist if done correctly and with dedication.  You'll simply be taking an oblique V-crunch and holding it for longer periods, and at the end of this two-week challenge, you will be holding it for a full minute.  Don't worry, if you're thinking to yourself that there is no way you can hold a move for very long, we're going to show you how to get there.

How to Perform the Oblique V-Crunch Hold

We asked Kendall Wood, NASM CPT and coauthor of Core Fitness Solution, for the best advice on how to make sure you do this move right.  Here's his simple, point-by-point breakdown.

• Step 1:  Lie down on your right side and place your left hand behind your head and your right hand on the floor beside you.
• Step 2:  Press your right hand into the floor, keep your legs together and straight, and raise them off the floor.
• Step 3:  Bring your torso toward your legs and hold this position as long as possible.  Breathe through it and keep your muscles engaged the entire time.
• Step 4:  When you feel like you can no longer hold this position with correct form, slowly lower your legs and torso back onto the floor.
• Step 5:  Repeat the same steps for the left side.

If you're a beginner and held that for even 10 seconds, you might be thinking, "That was pretty tough; how am I going to hold that for a whole minute?" Or you may be thinking that we've lost our minds to ask you to build up to one minute of holding this move.  Fret not!  It really is possible.  You'd be surprised just how quickly you'll gain strength and chisel away at your middle!

Building Up to a 60-Second Hold

No matter what your time is right now, you can always improve it.  According to Wood, you should "start where you are comfortable and then step out of your comfort zone just a bit every day."  Here's his two-week challenge on how to make your dream midsection.

The 2-Week Challenge

Don't worry if you can't quite build up as fast as the two-week plan suggests.  Do what you can and add one second at a time if you have to; just push yourself and keep going because challenge makes change.  As we add more muscle to our bodies, they become fat-burning machines.  The more muscle you have, the more calories you will burn, even while at rest.

Superstar personal trainer Jeanette Jenkins knows how to help her clients Amber Rose, Pink, Alicia Keys, and Tia Mowry stay in shape on tour, on the road, and wherever they are.  She knows you probably have a busy holiday season ahead, so she crafted this exclusive workout for you with some of her favourite total-body moves so you can stay in shape all season long, no matter where you are.  No equipment, no problem!  All you need is some space to move — a living room, park, backyard, or corner of your hotel room will do.

With each of these moves, Jeanette recommends doing 30 to 60 seconds, meaning you can be done in as little as three to six minutes!  If you have more time, she recommends repeating the circuit three times to get a calorie-blasting, body-strengthening sweat session in.

High Knees:  30-60 Seconds

• Run in place while lifting your knees high to the level of your waist.  Engage your abs as the knee comes up.
• Pump your arms to warm up your upper body.

Up-Down Planks with Core Rotation:  30-60 Seconds

• Come into a plank position with your arms and legs straight.  Your hands should be underneath your shoulders and your feet hips-width distance apart.
• Keep your torso parallel to the floor, and lower your right forearm to the mat and then the left, coming into elbow plank.
• Then step your right hand back onto the mat, and then the left, pushing yourself back up to plank position.
• Bring the opposite knee to the opposite elbow.

Jump Squats:  30-60 Seconds

• Stand with your feet shoulder-width apart.  Start by doing a regular squat, then engage your core and jump up explosively.
• When you land, lower your body back into the squat position to complete one rep.
• Land as softly as possible (this requires control).

Mountain Climbers:  30-60 Seconds

• Start in a traditional plank — shoulders over hands and weight on just your toes.
• With your core engaged, bring your right knee forward under your chest, with the toes just off the ground.  Return to your basic plank.  Switch legs, bringing the left knee forward.
• Keep switching legs and begin to pick up the pace until it feels a little like running in place in a plank position.

Push-Up to Side Plank:  30-60 Seconds

• Begin in plank position.
• Bend your elbows lowering into a push-up.
• Straighten your arms and lift your right arm toward the ceiling, twisting into a side plank to make a T shape with your body.
• Rotate back to plank, placing your right palm on the floor to lower into a push-up.
• This time as you straighten your arms, rotate to the left lifting the left up.  Return to plank.

Lateral Hops:  30-60 Seconds

• Make small jumps side to side as if you are jumping over an invisible line.

2016 was the year Simone Biles became America's (and the world's) sweetheart — and it wasn't just with her victorious win in Rio.  There were so many moments that contributed to the love we all have for Miss Biles, from her killer dance moves to her adorable smile and her affinity for sparkles and Zac Efron.  Let's take a look back at this year's best moments for the pint-size powerhouse.
