12 No-Equipment Moves for an Effective Home Workout

5. Plank (Forearm): Core stability and posture

The forearm plank trains the deep core muscles that support posture and spinal stability. Start on your forearms and toes, keeping elbows under shoulders. Form a straight line from head to heels. Pull the belly button slightly toward your spine and breathe steadily. Aim for quality holds rather than long poor-form planking. Begin with 20–30 seconds and build toward 60 seconds or longer as strength improves. If this is too much, drop the knees while keeping a neutral spine for a modified plank. To increase challenge, add shoulder taps or lift one foot briefly while maintaining a solid plank position. Programming tip: use planks at the start of circuits to reinforce core bracing, or as a finisher for core endurance. Listen to your body: if you feel lower-back sharp pain, rest and reassess form. Proper bracing protects the spine and improves how you sit and stand throughout the day.
