Struggling with fatloss exercises can be incredibly frustrating but being hardcore isn't the answer. A smarter way to get your body to do what you want is with exercise regression.
Regression (modification) simply means going back to the most basic form of an exercise. It requires that you check your ego at the door every time you train (at least for a few weeks) but the reward is well worth it.
Just last month I was struggling with the single leg squat to swoop, an exercise from my new bodyweight fat loss workout plan. I was beyond frustrated trying to force my body to do something it could not do (which is why I ended up in pain at the Neuromuscular therapist's office).
After this episode I decided I needed to train smarter so I regressed to the most basic form of the single leg squat and now 5 weeks later I can do a modified single leg squat to wheel and am slowly working my way back to a full single leg squat to swoop (swoop is much harder for me than wheel).
Watch the video below to see how hard the single leg squat portion of the exercise was for me, how I regressed this exercise and the end result.
Remember that your body will not burn fat if your technique stinks so much that you're causing damage so make sure to go back to basics any time you are struggling with something new. You'll avoid pain, injuries, and eventually progress much faster.
