True North is a no-equipment strength and tone circuit that keeps you standing from start to finish: 10 lunges, 10 calf raises, 10 more lunges, then a three-part shoulder block of 10 arm circles, 10 wide arm circles and 10 more arm circles, capped with 10 bicep extensions. Simple movements, held to a steady bearing.

The lower body work sandwiches calf raises between two sets of lunges, so your calves fire while your quads and glutes recover just enough - and the second set of lunges lands on legs that never fully reset. The upper body block does the same thing with amplitude instead of load: small circles fatigue your deltoids with constant tension, wide circles then demand a much larger range on shoulders already burning, and the return to small circles feels entirely different the second time around. That is the trick of unloaded shoulder work - the weight of your own arms becomes surprisingly heavy when the muscle is never allowed to switch off. The bicep extensions at the end run on the same principle: self-generated tension, no equipment required.

Lunge with a tall torso and let your back knee travel straight down. On calf raises, rise all the way onto the balls of your feet and lower with control rather than dropping - the descent is half the exercise. Keep your arms locked straight and at shoulder height through every circle; the moment they drift downward, the exercise gets easier and gives you less. In bicep extensions, clench your fists hard and fight your own arm through the full range.

A compass is only useful if you keep checking it. Same bearing, every session, and you will get where you are going.

Make it Harder: Hold a filled water bottle in each hand for the entire arm circle block.

Make it Easier: Cut each arm circle set to 5 reps and build back up over time.
