Jackknife

I have another core exercise for you for this weeks Home Exercise of the Week.  It’s called a Jackknife and it’s one of the more challenging ab exercises but once you get the hang of it you will feel how effective it is!

The Jackknife works all areas of your core as well as your hip flexors and at the same time it isometrically works your upper body muscles.  This exercise can put a lot of strain on your lower back if not done correctly so let’s take a look at the key points to doing it properly.

  • getting on the stability ball can be challenging so the best way is to put your hands on the floor and one leg up on the ball first then put your other leg up.  Your shins should be resting on the ball.
  • it is very important to keep your abs contracted by pulling your belly button in towards your spine.  This will help keep your hips from sagging down which will put a lot of pressure on your lower back.
  • once you have stabilized yourself, pull your knees slowly in towards your chest squeezing the abs and then return slowly to the starting position
  • if you find it hard to do this exercise with your hands on the floor, try using a bench to rest your arms on.  This raises you up a bit and can take some of the pressure off your upper body

So there you have the key points to doing the Jackknife effectively.  Add this to your routine and you will be well on your way to a strong and toned core!  If you want an extra challenge and some extra upper body work, try adding a pushup in between each roll in.  You can also do a side roll to target your obliques more but that is a video for another day! 🙂

Jump Lunge Hold

Hello everyone!  It’s time again for the Home Exercise of the Week.  I have a killer thigh burning and sweat inducing exercise for you today!  It’s called the Jump Lunge Hold and if the jumping part doesn’t cause you to shout profanities then the hold will. 😉

The Jump Lunge Hold is going to strengthen and build your quadriceps, hamstrings, glutes, and calves.  The hold is going to build muscular endurance and the jumping adds a plyometric aspect to the exercise increasing your explosive power and heart rate.  So overall this is a great leg exercise to add in to your routine and can be done anywhere with or without weights.

How to do this leg burner effectively:

  • keep your body upright with your chest out and back straight throughout
  • lunge down until both legs are at 90 degree angles
  • jump up pushing through the heel of your front foot
  • switch legs in the air and try to land softly keeping your weight distributed between your front foot and back toes
  • hold the lunge position for 3 to 5 seconds before switching legs

So that’s it for the Jump Lunge Hold.  Give it a try and I guarantee that it will strengthen and burn your thighs and butt!  If you are in one of my boot camps or a one on one client then you have this exercise to look forward to in your next session!  Happy lunge jumping. 🙂

 

One Arm Plank Shoulder Circles

It’s time to get your core and shoulders working with this Home Exercise of the Week!  In the video you’ll notice that this exercise has a really long name! (obviously at the time of filming it I couldn’t think of anything better)  So instead I have shortened it to One Arm Plank Shoulder Circles.

I’m going to be honest with you and say this exercise is hard!  That being said there are modifications to make it easier until you get stronger.

The plank part of the exercise is isometric which means the joint angle and muscle length doesn’t change during contraction.  This is really going to work your core!  The shoulder circle part of the exercise works your deltoids and in particular, your posterior deltoid and upper back muscles.

Let’s take a look at the key points to remember when doing One Arm Plank Shoulder Circles.

  • keep your feet wide to stabilize yourself during the movement
  • keep your body straight throughout (no butts sticking up!)
  • pull your belly button in towards your spine to keep your abdominal muscles flexed
  • raise one arm out to the side keeping it in line with your upper body
  • move your arm in small circles at an even, medium pace (this is going to burn!)
  • start by doing forward circles for 10 to 20 seconds or for 15 to 20 repetitions then go backwards for the same amount of time or reps
  • breath deeply and evenly throughout the exercise

As I mentioned earlier, there is a way to make the exercise easier if you are having trouble.  To do this, put your knees on the floor instead of being on your toes.  Keep in mind though that you still need to keep your body straight with this modification so no bending at the waist.

So there you have One Arm Plank Shoulder Circles!  If you have progressed to the point where this exercise is starting to get easy, try holding on to a dumbbell when doing the shoulder circles.  This will step up the intensity and maybe even cause you to utter some profanity while doing it!

5 Squat Hold

This weeks Home Exercise of the Week is a variation of the regular body weight squat.  The 5 Squat Hold is an exercise that I like to add in to my training sessions and boot camps from time to time so people have another reason to curse and swear at me!  I can just picture it now…sweaty people groaning, complaining, and wondering why they ever decided to do this. 😉

All kidding aside, the 5 Squat Hold is effective.  You will be sculpting and strengthening your quads, hamstrings, and glutes.  On top of all that, the hold part of the exercise will increase your muscular endurance.  The benefits far outweigh the temporary pain and discomfort.

With any exercise, strict form is top priority.  Some key points to remember when doing the 5 Squat Hold:

  • Have your feet shoulder width apart with your toes pointed out slightly
  • Squat down like you’re going to sit in a chair keeping your knees in line or behind your toes
  • Stay as upright as possible.  There is a tendency when squatting to lean over too much.  Try to avoid this as doing so can hurt your lower back.  To stay upright, stick your chest out, keep your head looking forward, and arch your back up slightly.
  • Come down until your thighs are parallel to the floor.  If you can’t go down that far at first just do what you can and over time you will be able to go lower
  • As you are coming up out of the squat make sure that you are pushing up through your heels.  If you push up through your toes, a lot of stress will be placed on your knees.  We don’t want that!  Pushing through the heel will put more of the strain on the working muscles

In the video, I said to hold for 5 seconds.  That is a good time to start off with but if you want more of a challenge take each hold to 10 seconds.  1 set of this exercise would be 5 squats with a 5 – 10 second hold for 3 – 4 times through giving you 15 to 20 repetitions of squats total.  To get a shoulder workout at the same time, hold your arms in front of you at shoulder height throughout the exercise and they will be burning too!

So there you have the 5 Squat Hold.  Fire up your legs and let me know how you do!

Wall Sit Shoulder Press

It’s time for another Home Exercise of the Week!  Get your legs and shoulders fired up with the Wall Sit Shoulder Press.

From the video, it may look simple enough but don’t let that fool you…this will burn!  Grown men have almost cried because of the wall sit, curses have been vocalized through clenched teeth, and sweat has poured down grimaced faces.  I know it sounds horrible and you might be thinking “Craig, why would I ever want to put myself through that?”.

Well the answer to your question is you will gain more strength and endurance in your legs, you will increase strength and mobility in your shoulders, and you will strengthen the deep core muscles of your trunk and your spinal muscles.  All that plus if you’re weird like me, you might even think it’s fun! (Ok I’ll be honest…it’s more fun making people do it than actually doing it!)

The wall sit portion of this exercise is isometric which means you are working your muscles without any movement at the joint.  This is great for building strength and endurance.

Some key points to remember when doing the Wall Sit Shoulder Press:

  • make sure your knees are directly over your ankles
  • slide down the wall until your thighs are parallel to the floor
  • keep your back pressed firmly against the wall
  • press your arms back against the wall as much as you can throughout the movement (you may not be able to maintain contact with the wall throughout the exercise at first but over time your mobility will increase)
  • exhale as your press up and inhale as you lower your arms

So there you have the Wall Sit Shoulder Press.  Start with a couple sets of 12 repetitions or a couple of timed sets of 30 seconds at the end your leg or shoulder workout and feel the burn!
