Aries is a cardio and strength circuit for the zodiac's ram - the sign that solves every problem by going straight through it: 10 high knees, 10 climbers, 10 more high knees, 6 power squats, 10 calf raises, 6 more power squats, and 2+ push-ups to finish. It opens at a run and never really slows down.

The circuit charges hard from the first second, which is pure Aries: high knees and climbers back to back put your heart rate at altitude before anything resembling strength work begins. Then the power squats arrive in two sets of 6 with calf raises wedged between - the calf raises are not a break, they are a different fight, loading the lower leg while your quads and glutes catch just enough breath to hit the second squat set properly. Power squats reward aggression: a fast, driven rise out of the bottom recruits more muscle than a polite one. The closing 2+ push-ups are an open-ended challenge flag planted at the end of the circuit - two is the entry fee, and a ram never pays just the entry fee.

Drive knees to hip height in high knees and stay on the balls of your feet. Keep hips low and level in climbers - the knee drive should come to your chest, not your chest dropping to meet it. In power squats, hit full depth with arms extended forward, then stand up like you mean it. Push-ups travel the full range, chest low, body in one line; every rep past two should look identical to the first.

The ram doesn't look for the gate. Head down, straight through - all sets, plus sign honored.

Make it Harder: Raise the push-up floor from 2+ to 6+.

Make it Easier: Slow the high knees to a march and do the push-ups against a wall or from your knees.
