Beginner Strength Training Tips for Limiting Knee Pain During Hiking

North and West Vancouver are prime destinations for hiking because the mountains are very accessible. Some of our clients live next door to several different trails and enjoy this activity from the spring up until the first snowfall. Knee pain may be experienced while hiking; it can largely be prevented with proper exercise progressions.

Chronic knee pain, not associated with direct trauma such as a fall or twist, is often a result of long-term muscle imbalances. If you are experiencing pain that is either getting worse or not getting any better, have your doctor or physiotherapist assess it. As Kinesiologists, we look at the entire chain of movement. This means watching clients move while doing strength and flexibility tests to discover where muscle imbalances are.

Assessments include overhead squats and single-leg squats. Some things that show up are weak outer hips/tight inner hips, tight hip flexors/weak glutes, weak quadriceps/tight hamstrings and tight calf muscles. When these movements are not completed in a balanced and optimal manner, we first address any muscle tightness or weakness to develop smoother, more functional movement patterns. This is much before any type of loading is done; body weight is often enough.

Areas to focus on are: Quadriceps, Hamstrings, Calves, Glutes and Upper Body. The following are some suggestions. Remember to let joint pain be your guide; be aware of your own limits and start gradually. A little muscle discomfort is a sign that you are challenging your body; it is when you rest the following day that your body adapts. We suggest that anyone unfamiliar with these exercises hire a Kinesiologist or knowledgeable Personal Trainer.

If you are new to weight training or are rehabilitating from an injury, start with the beginner exercises.

Phase I - Isolated Beginner (4 weeks):
To fatigue (when form fails), 1-3 sets, 60-second rest between sets or complete as a circuit. 2-3 days per week with one day of rest, e.g., cardio or light physical activity, in between.
  1. Side Lying Leg Raises: Lie on your side. Keep your ribs lifted and your core in neutral. Your hips are stacked on top of each other and your bottom leg is bent. Exhale to lift the top leg up towards ceiling and slightly behind, inhale to lower. Tip: Complete this with your back to a wall. Gently press your heel against the wall while lifting and lowering.
  2. Clams: Start is the same as above, but with both knees bent and heels touching. Exhale to raise the top knee up, keeping the heels together. Don't rotate hips.
  3. 4-Point Kneeling or Pointed Dog: Start on your hands and knees; hands under shoulders, knees under hips. Keep your pelvis in neutral and engage your core. Exhale to reach one leg back. Focus on using your buttocks to raise the leg only as far as neutral is maintained. Alternate sides. Bend your arms, placing the forearms on the mat. Lie on a ball if it's difficult for your wrists.
  4. Shoulder Bridge: Lie on your back with your arms by your side, knees bent, and heels hip-distance apart and slightly in front of the knees. Keeping your spine in neutral, exhale to use your glutes (buttocks) to raise the hips; inhale to relax your glutes and lower. Be aware of any rotation of the pelvis or if the knees are dropping or moving out to the side. Keep legs parallel to each other.
Phase II - Integrated Beginner (4 weeks)
12-15 reps, 1-3 sets, 60-second rest between sets or complete as circuit. 2-3 days per week with one day of rest , e.g., cardio or light physical activity in between.
  1. Stability Ball Wall Squats
  2. Seated Leg Curls or Lying Leg Curls (single-leg)
  3. Leg Press (single-leg) - keep legs parallel, finish with a slight bend in leg.
  4. Standing Calf Raise (body weight)
  5. Leg Extension (single-leg) - use the thigh, the lift the bar up, finish with slight bend in leg.
  6. Stiff Leg Deadlift (body weight, use a dowel or broomstick to start)**
  7. Stationary Lunges or Step-Ups
Progress gradually by adding 5% resistance when the last repetition is easy. Try using 5-lb dumbbells for the step-ups or lunges.

We recommend single-leg because strength imbalances show up. If one side is noticeably stronger, try one set for the stronger side and two to three for the weaker side.

** Many people have difficulty completing the proper hip hinge. Stiff Leg Deadlifts need to be done with the spine straight, and the core engaged. Lifting is done with the hamstrings and glutes. We often see this exercise done incorrectly in the gym. Hire someone to teach you and watch this video of a proper Romanian deadlift.

Hip and thigh strength are important to develop for hiking. The hip drive is used to propel you up the mountain while strong thighs are especially needed to prevent too much loading when going downhill.

There are many progressions from the two phases here. We would be happy to answer any questions as well, just leave a comment below. Anyone in the Vancouver area who wants a personalized program designed by a Lifemoves Kinesiologist, please email us.

Top 10 Tips to Prevent Back Injuries During Lifting


Here are ten easy steps you can take to prevent back injuries during lifting. I thought about them when I was part of a team of over 100 volunteers who were taking down the Biathlon Venue at the Vancouver 2010 Winter Olympics.

My dreams came true this February; I made it to the Olympics. It takes a very large team of dedicated people to put up and take down all the temporary fencing, start/finish line, and course markers range and get the stadium ready to make the Biathlon Venue function for the sport, television and spectators.

I had participated in the Olympics as an Anti-Doping escort for the athletes throughout the games. After my job was done, I heard that the stage crew had plans to take down the range and stadium in an hour and a half -- a sizable task. Volunteers ranged from the fit who were used to manual labour to the unfit who were not used to lifting tasks. Even though I was not part of the stadium or range crew, I stuck around to give everyone an extra set of hands and make a further contribution to the Olympics.

The enthusiasm of the volunteers really struck me. We all bonded together and, unified in our goal, worked really well as a team. Some of things we had to move were awkward wooden scoring tables, v-boards (blue lane course markers) and 6 x 4 feet pieces of wooden fencing which had to be carefully packed and stored in a hut down a hill for future events. While I was participating, I observed that many of the other volunteers didn't seem to know how to lift, push, or pull properly, thus putting themselves at risk for injury. My concern for their well being inspired this list.

Follow these 10 tips to help prevent back injuries.

1. Keep Close: The farther the item that you are lifting is away from your body, the greater the effort and strain that is placed on your back. Change positions so that you are as close as possible to what you are lifting.

2. Bend Your Knees: Always try to use the bigger muscles in your lower-body to do most of the lifting, and keep your spine in a neutral position. Deadlifts and Stiff Leg Deadlifts are great training for this. Seek professional help learn the proper technique.

3. Stay in the Box: To reduce the stress on your body, carry heavier items between your mid-chest and mid-thighs. Use a step-stool or ladder if you need to lift something over your head. This will keep the heavier items close to your body.

4. Use Both Hands: If you can, use both hands when lifting or pushing heavy or awkward items. This splits the load on your spine and engages muscles on both sides of your body.

5. Limit Twist: Rotation of the spine is a natural movement used in many sports and occupations, but if you are not used to twisting that much or have a limited range of motion, it can place you in harm's way. Try to make sure that your body is directly facing whatever you are lifting or pulling.

6. Pivot Hips: If you have to move something from one side to another, shift it by rotating your hips. For example, lift your right heel to pivot your hips if you're moving the item from right to left; lift your left heel if you're going from left to right. Your hips will shift with the object you're moving, reducing the risk of injury.

7. Take Breaks, Change Tasks, Change Positions: Muscle and ligament fatigue is one reason we end up with an injury. Many jobs are highly repetitive -- for example, someone loading warehouse shelves all day or an iron worker bent over in one position for long periods of time. Repetitive motion causes the tissue to fatigue in the same way that bending a twig over and over or simply holding it in a bent position for several minutes will cause it to eventually break.

8. Ask for Help: It is better to distribute the effort between two or three people rather than trying to lift something that is very awkward or too heavy for you. Another option is to use pulleys, a cart or machinery like a winch or a snowmobile rig. Unless you are trained, 45lbs is the maximum weight that the general population should be lifting at one time, to reduce the risk for injuries.

9. Engage the Core: Core strength comes from the ability to activate the proper sequence of muscles for the intensity needed. This creates the appropriate amount of intra-abdominal pressure to stabilize the spine when pushing, pulling, lifting or rotating. The outer muscle layers like the obliques are used for movements like rotation and side-bending. Read Getting to the Core of Reducing Back Pain for more information.

10. Keep the Back Straight: Flexion, extension and rotation are natural ranges of motion for the back. We also have natural curves in our backs. Many people I see have trouble differentiating hip flexion/extension with spine extension/flexion. Stand tall, keep the vertebrae still while tilting your pelvis back and forth like a bowl. It rotates around your femurs (thigh bones). Keep the back straight (with the crown of your head reaching away from the tailbone in a straight line) and in neutral (restoring the natural curves in your spine).

We had chain of people who were about two feet apart handing each other wood blocks for the load out. Other groups pushed the sleds the last few feet after they were dropped off by snowmobiles. To my knowledge, this all happened without injuries.

Keep these tips in mind to reduce your chances of a back injury. If you are recovering from a back injury, or want a Lifemoves Kinesiologist to show you more ways to move properly so you can stay active, please fill out a consultation form or email us at consultations@lifemoves.ca
