Free 7 minute timer for the famous 7-minute workout and quick tasks. Scientific workout timing made easy.
The 7-minute workout is a scientifically designed high-intensity circuit training routine published in the American College of Sports Medicine journal. It consists of exactly 12 exercises done for 30 seconds each with 10 seconds rest between exercises totaling 420 seconds or 7 minutes. The workout hits all major muscle groups in a specific sequence that alternates between upper body, lower body, and core to allow brief recovery while maintaining high intensity throughout. Research shows this specific timing and exercise selection provides meaningful fitness benefits in minimal time.
Seven minutes alone won't transform you dramatically but it's legitimately effective for maintaining fitness or getting started on an exercise program. The ACSM research showed 7-minute HIIT circuits provided similar cardiovascular benefits to longer moderate workouts due to the high intensity. The catch is you have to actually go hard during those 30-second intervals, not just casually go through motions. I do the 7-minute workout 2-3 times with 2-minute rests between rounds for a more complete 30-minute session. For busy days one round is genuinely better than nothing.
The original 12 exercises in order are: jumping jacks, wall sit, pushups, ab crunches, step-ups onto chair, squats, tricep dips on chair, plank, high knees, lunge, pushup with rotation, and side plank on each side. Each exercise is 30 seconds with 10 seconds to transition to the next one. The specific sequence alternates muscle groups intentionally so you can maintain intensity - for example a hard leg exercise followed by upper body lets legs recover briefly. I keep the official sequence on my phone and follow it exactly because the order really does matter for performance.
You only need your body weight, a wall, and a sturdy chair - no gym or fancy equipment required which is part of why this workout became so popular. The wall sit obviously requires a wall, tricep dips need a chair, and step-ups can use a chair or sturdy stairs. Everything else is pure bodyweight. The timer is actually the most important equipment" because precise 30-second intervals are crucial to the workout structure. I've done it hundreds of times with just my phone timer and whatever furniture happens to be around me."
Beginners should absolutely modify - I started with 20-second work intervals instead of full 30 seconds and did easier variations like knee pushups instead of full pushups. The key is maintaining the circuit structure and working at appropriate intensity for your current fitness level. Going too hard too fast leads to injury or burnout and quitting. After a couple weeks of modified versions I could handle the full 30-second intervals at proper intensity. Some people start with just one round and gradually build up to multiple rounds over time.
