The supine knee-in is an effective abdominal exercise when performed correctly. In most gyms, people hold a medicine ball or dumbbell between their feet for resistance, but since the weight acts downward, it tends to over-activate the hip flexors just to keep the weight off the ground. A better option is to use horizontal loading…

I just completed my CPR certification this past weekend. I have to renew it every year for one of my professional designations, and I believe everyone should do the same—regardless of their occupation. I once had to perform first aid on a baby, and I’m grateful I knew what to do. One of the key…

Unless a planned layoff follows a training cycle, you should always taper in the final workout by performing 30–50% fewer sets than the previous session. If done correctly, even with half the sets, the total workload won’t drop much (if at all). However, selecting the right load is crucial—it’s as much an art as it…

Why do some people experience great results with certain supplements while others do not? Let’s look beyond the obvious—where one person may have a greater dietary need than another. For example, a vegetarian may require more creatine than a heavy meat-eater and will typically see better results from supplementation. But what if you have two…

Start with a low step beside you and use only your bodyweight at first. As your strength and stability improve, you can progress to holding a pair of dumbbells. Keep your hips level throughout the movement. If the step is too high, maintaining this position will be difficult. A common mistake is pushing off with…

In strength training, time under tension (TUT), sometimes called time under load, refers to the total duration of a set. It’s calculated by multiplying the number of reps by the tempo of each rep. For example, if you perform 10 reps and each rep takes 6 seconds (2 seconds to lift the weight and 4…
