Ten Effective No-Equipment Exercises to Help You Live Paleo
Step-ups are a great way to strengthen your thighs and knees.
1. Standing in front of a bench or staircase, place your foot flat on the stair or bench. Push into your heel and bring your other foot up to the step, but don't put any weight on that foot — just tap your toe.
2. Keeping your first foot planted flat on the stair or bench, place the other foot gently back down to the floor. Come up and down eight to ten times, just tapping the toe of your other foot on the step.
3. Repeat on the other side.
