Isometric leg exercises don't seem hard at first, but the longer you hold, the harder they are.
Image Credit: FreshSplash/E+/GettyImages Isometric exercises — like planks or wall sits where you contract a muscle and hold it — are an effective way to build muscular strength and endurance. They can also help improve your posture and balance, says certified personal trainer Liza McAllister of Levelled with Liza.

"I personally never discount isometrics in any workout," she says. "The challenge is physically and mentally very satisfying. One of my new favorite isometric exercises is the bear plank."

Do: each move for 30 seconds before going on to the next. Complete the entire circuit twice. Do your left leg on the first round and the right leg on the second round.
Tip Maintain good posture with a straight spine. Softening your knees will help with balance when necessary. Don’t lock your knees if you feel wobbly. If you want to increase the intensity, do a few pulses at the end of each move. Only shift as far as you can control your body weight, and keep your core engaged.
